AH-64 Apache
Function: Fire support and security for forward and rear area forces, point target/anti-armor, anti-helicopter, armed escort, supporting arms control and coordination, point and limited area air defense from enemy fixed-wing aircraft, armed and visual reconnaissance.
History: Apache production began in 1982 and the first unit was deployed in 1986. As of November 1993, 807 Apaches were delivered to the Army. The last Army Apache delivery is scheduled for December 1995. Thirty-three attack battalions are deployed and ready for combat. The Army is procuring a total of 824 Apaches to support a new force structure of 25 battalions with 24 Apaches for each unit (16 Active; two Reserve; seven National Guard) under the Aviation Restructure Initiative. The Apache has been sold to Israel, Egypt, Saudi Arabia, the UAE, and Greece.
Description: The Boeing (McDonnell Douglas) (formerly Hughes) AH-64A Apache is the Army's primary attack helicopter. It is a quick-reacting, airborne weapon system that can fight close and deep to destroy, disrupt, or delay enemy forces. The Apache is designed to fight and survive during the day, night, and in adverse weather throughout the world. The principal mission of the Apache is the destruction of high-value targets with the HELLFIRE missile. It is also capable of employing a 30MM M230 chain gun and Hydra 70 (2.75 inch) rockets that are lethal against a wide variety of targets. The Apache has a full range of aircraft survivability equipment and has the ability to withstand hits from rounds up to 23MM in critical areas.
The AH-64 Apache is a twin-engine, four bladed, multi-mission attack helicopter designed as a highly stable aerial weapons-delivery platform. It is designed to fight and survive during the day, night, and in adverse weather throughout the world. With a tandem-seated crew consisting of the pilot, located in the rear cockpit position and the co-pilot gunner (CPG), located in the front position, the Apache is self-deployable, highly survivable and delivers a lethal array of battlefield armaments. The Apache features a Target Acquisition Designation Sight (TADS) and a Pilot Night Vision Sensor (PNVS) which enables the crew to navigate and conduct precision attacks in day, night and adverse weather conditions. The Apache can carry up to 16 Hellfire laser designated missiles. With a range of over 8000 meters, the Hellfire is used primarily for the destruction of tanks, armored vehicles and other hard material targets. The Apache can also deliver 76, 2.75" folding fin aerial rockets for use against enemy personnel, light armor vehicles and other soft-skinned targets. Rounding out the Apache?s deadly punch are 1,200 rounds of ammunition for its Area Weapons System (AWS), 30MM Automatic Gun.
Powered by two General Electric gas turbine engines rated at 1890 shaft horsepower each, the Apache?s maximum gross weight is 17,650 pounds which allows for a cruise airspeed of 145 miles per hour and a flight endurance of over three hours. The AH-64 can be configured with an external 230-gallon fuel tank to extend its range on attack missions, or it can be configured with up to four 230-gallon fuel tanks for ferrying/self-deployment missions. The combat radius of the AH-64 is approximately 150 kilometers. The combat radius with one external 230-gallon fuel tank installed is approximately 300 kilometers [radii are temperature, PA, fuel burn rate and airspeed dependent]. The AH-64 is air transportable in the C-5, C-141 and C-17.
An on-board video recorder has the capability of recording up to 72 minutes of either the pilot or CPG selected video. It is an invaluable tool for damage assessment and reconnaissance. The Apache's navigation equipment consists of a doppler navigation system, and most aircraft are equipped with a GPS receiver.
The Apache has state-of-the-art optics that provide the capability to select from three different target acquisition sensors. These sensors are
- Day TV. Views images during day and low light levels, black and white.
- TADS FLIR. Views thermal images, real world and magnified, during day, night and adverse weather.
- DVO. Views real world, full color, and magnified images during daylight and dusk conditions.
The Apache has four articulating weapons pylons, two on either side of the aircraft, on which weapons or external fuel tanks can be mounted. The aircraft has a LRF/D. This is used to designate for the Hellfire missile system as well as provide range to target information for the fire control computer's calculations of ballistic solutions.
Threat identification through the FLIR system is extremely difficult. Although the AH-64 crew can easily find the heat signature of a vehicle, it may not be able to determine friend or foe. Forward looking infrared detects the difference in the emission of heat in objects. On a hot day, the ground may reflect or emit more heat than the suspected target. In this case, the environment will be "hot" and the target will be "cool." As the air cools at night, the target may lose or emit heat at a lower rate than the surrounding environment. At some point the emission of heat from both the target and the surrounding environment may be equal. This is IR crossover and makes target acquisition/detection difficult to impossible. IR crossover occurs most often when the environment is wet. This is because the water in the air creates a buffer in the emissivity of objects. This limitation is present in all systems that use FLIR for target acquisition.
Low cloud ceilings may not allow the Hellfire seeker enough time to lock onto its target or may cause it to break lock after acquisition. At extended ranges, the pilot may have to consider the ceiling to allow time for the seeker to steer the weapon onto the target. Pilot night vision sensor cannot detect wires or other small obstacles.
Overwater operations severely degrade navigation systems not upgraded with embedded GPS. Although fully capable of operating in marginal weather, attack helicopter capabilities are seriously degraded in conditions below a 500-foot ceiling and visibility less than 3 km. Because of the Hellfire missile's trajectory, ceilings below 500 feet require the attack aircraft to get too close to the intended target to avoid missile loss. Below 3 km visibility, the attack aircraft is vulnerable to enemy ADA systems. Some obscurants can prevent the laser energy from reaching the target; they can also hide the target from the incoming munitions seeker. Dust, haze, rain, snow and other particulate matter may limit visibility and affect sensors. The Hellfire remote designating crew may offset a maximum of 60 degrees from the gun to target line and must not position their aircraft within a +30-degree safety fan from the firing aircraft.
The Apache fully exploits the vertical dimension of the battlefield. Aggressive terrain flight techniques allow the commander to rapidly place the ATKHB at the decisive place at the optimum time. Typically, the area of operations for Apache is the entire corps or divisional sector. Attack helicopters move across the battlefield at speeds in excess of 3 kilometers per minute. Typical planning airspeeds are 100 to 120 knots during daylight and 80 to 100 knots at night. Speeds during marginal weather are reduced commensurate with prevailing conditions. The Apache can attack targets up to 150 km across the FLOT. If greater depth is required, the addition of ERFS tanks can further extend the AH-64's range with a corresponding reduction in Hellfire missile carrying capacity (four fewer Hellfire missiles for each ERFS tank installed).
The Russian-developed Mi-24 HIND is the Apache's closest couterpart. The Russians have deployed significant numbers of HINDs in Europe and have exported the HIND to many third world countries. The Russians have also developed the KA-50 HOKUM as their next generation attack helicopter. The Italian A-129 Mangusta is the nearest NATO counterpart to the Apache. The Germans and French are co-developing the PAH-2 Tiger attack helicopter, which has many of the capabilities of the Apache.
The AH-64A: The AH-64 fleet consists of two aircraft models, the AH-64A and the newer Longbow Apache (LBA), AH-64D. AH-64A model full-scale production began in 1983 and now over 800 aircraft have been delivered to the U.S. Army and other NATO Allies. The U.S. Army plans to remanufacture its entire AH-64A Apache fleet to the AH-64D configuration over the next decade. The AH-64A fleet exceeded one million flight hours in 1997, and the median age of today's fleet is 9 years and 1,300 flight hours.
The AH-64A proved its capabilities in action during both Operation Restore Hope and Operation Desert Storm. Apache helicopters played a key role in the 1989 action in Panama, where much of its activity was at night, when the AH-64's advanced sensors and sighting systems were effective against Panamanian government forces.
Apache helicopters also played a major role in the liberation of Kuwait. On 20 November 1990, the 11th Aviation Brigade was alerted for deployment to Southwest Asia from Storck Barracks in Illesheim Germany. The first elements arrived in theater 24 November 1990. By 15 January 1991 the unit had moved 147 helicopters, 325 vehicles and 1,476 soldiers to the region. The Apache helicopters of the Brigade destroyed more than 245 enemy vehicles with no losses.
During Operation Desert Storm, AH-64s were credited with destroying more than 500 tanks plus hundreds of additional armored personnel carriers, trucks and other vehicles. They also were used to destroy vital early warning radar sites, an action that opened the U.N. coalition's battle plan. Apaches also demonstrated the ability to perform when called upon, logging thousands of combat hours at readiness rates in excess of 85 percent during the Gulf War.
While recovery was ongoing, additional elements of the 11th Aviation Brigade began the next chapter of involvement in the region. On 24 April 1991 the 6th Squadron, 6th Cavalry?s 18 AH-64 helicopters began a self-deployment to Southwest Asia. The Squadron provided aerial security to a 3,000 square kilometer region in Northern Iraq as part of the Combined Task Force of Operation Provide Comfort.
And the AH-64A Apache helped to keep the peace in Bosnia. April of 1996 saw the beginning of the 11th Regiment?s involvement in Bosnia-Herzegovina. Elements of 6-6 Cavalry served as a part of Task Force Eagle under 1st Armored Division for 7 months. In October of 1996, Task Force 11, consisting of the Regimental Headquarters, 2-6 Cavalry, 2-1 Aviation and 7-159 Aviation (AVIM) deployed to Bosnia-Herzegovina in support of Operation Joint Endeavor/Operation Joint Guard for eight months. In June of 1998 the Regimental Headquarters, 6-6 Cav and elements of 5-158 Aviation were again deployed to Bosnia-Herzegovina in support of Operations Joint Guard and Joint Forge for 5 months. The AH-64A?s advanced sensors and sighting systems proved effective in removing the cover of darkness from anti-government forces.
Army National Guard units in North and South Carolina, Florida, Texas, Arizona, Utah and Idaho also fly Apache helicopters. The Army has fielded combat-ready AH-64A units in the United States, West Germany and in Korea, where they play a major role in achieving the US Army's security missions.
By late 1996, McDonnell Douglas Helicopters delivered 937 AH-64A Apaches -- 821 to the U.S. Army and 116 to international customers, including Egypt, Greece, Israel, Saudi Arabia and the United Arab Emirates.
The Apache is clearly one of the most dynamic and important programs in aviation and the Army, but it is not without limitations. Due to the possibility of surging the engines, pilots have been instructed not to fire rockets from in-board stations. According to current doctrine, they are to fire no more than pairs with two outboard launchers every three seconds, or fire with only one outboard launcher installed without restrictions (ripples permitted). These are the only conditions permitted. Other firing conditions will be required to be approved via a System Safety Risk Assessment (SSRA).
The improvement of aircraft systems troubleshooting is a high priority issue for O&S Cost reduction. Because of funding cuts, the level of contractor support to the field has been reduced. This results in higher costs in no fault found removals, maintenance man hours, and aircraft down time. The Apache PM, US Army Aviation Logistics School, and Boeing are currently undertaking several initiatives. Upgrading and improving the soldier's ability to quickly and accurately fault isolate the Apache weapons system is and will continue to be an O&S priority until all issues are resolved.
Prime Vendor Support (PVS) for the entire fleet of AH-64s is a pilot program for the Army, and may become a pilot program for the Department of Defense. PVS will place virtually all of Apache's wholesale logistic responsibility under a single contract. The Apache flying hour program will provide upfront funding for spares, repairables, contractor technical experts, and reliability improvements. Starting at the flight line there will be contractor expert technicians with advanced troubleshooting capability assigned to each Apache Battalion. At the highest level, PVS represents a single contractor focal point for spares and repairs. The intent is to break the current budget and requirements cycle that has Apache at 67% supply availability with several thousand lines at zero balance.
Modernization Through Spares (MTS) is a spares/component improvement strategy applied throughout the acquisition life cycle and is based on technology insertion to enhance systems and extend useful life while reducing costs. The MTS initiative seeks to leverage current procurement funds and modernize individual system spares thereby incrementally improving these systems. MTS is accomplished via the "spares" acquisition process. MTS, a subset of acquisition reform, seeks to improve an end item's spare components. The emphasis is on form, fit and function, allowing a supplier greater design and manufacturing flexibility to exploit technology used in the commercial marketplace.
Apache MTS focuses on the insertion of the latest technology into the design and manufacture of select spares. This is to be accomplished without government research and development (R&D) funds, but rather, uses industry investment. Industry, in turn, recoups this investment through the sale of improved hardware via long term contracts.
Modernization efforts continue to improve the performance envelope of the AH-64A while reducing the cost of ownership. Major modernization efforts within the AH-64A fleet are funded and on schedule. GG Rotor modifications were finished in April 1998,, and future improvements such as a Second Generation FLIR, a High Frequency Non-Line of Sight NOE radio, and an internal fully crashworthy auxiliary fuel tank are all on the verge of becoming a reality for the Apache.
The Aviation Mission Planning System (AMPS) and the Data Transfer Cartridge (DTC) are tools for the Embedded Global Positioning Inertial Navigation Unit (EGI) equipped AH-64A aircraft that allow aircrews to plan missions and download the information to a DTC installed in the Data Transfer Receptacle (DTR). This saves the pilots a lot of "fat fingering" and eliminates the worry of everyone being on the same "sheet of music". Other features of the DTC include; saving waypoints and targets and troubleshooting. The EGI program is a Tri-service program with the Army, Air Force and Navy.

UH-60 Blackhawk
Description: The Black Hawk is the Army?s front-line utility helicopter used for air assault, air cavalry, and aeromedical evacuation units. It is designed to carry 11 combat-loaded, air assault troops, and it is capable of moving a 105-millimeter howitzer and 30 rounds of ammunition. First deployed in 1978, the Black Hawk?s advanced technology makes it easy to maintain in the field. The Black Hawk has performed admirably in a variety of missions, including air assault, air cavalry and aeromedical evacuations. In addition, modified Black Hawks operate as command and control, electronic warfare, and special operations platforms.
The Black Hawk is the primary division-level transport helicopter, providing dramatic improvements in troop capacity and cargo lift capability compared to the UH-1 Series "Huey" it replaces. The UH-60A, with a crew of three, can lift an entire 11-man fully-equipped infantry squad in most weather conditions. It can be configured to carry four litters, by removing eight troop seats, in the MedEval role. Both the pilot and co-pilot are provided with armor-protective seats. Protective armor on the Black Hawk can withstand hits from 23mm shells. The Black Hawk has a cargo hook for external lift missions. The Black Hawk has provisions for door mounting of two M60D 7.62mm machine guns on the M144 armament subsystem, and can disperse chaff and infrared jamming flares using the M130 general purpose dispenser. The Black Hawk has a composite titanium and fiberglass four-bladed main rotor, is powered by two General Electric T700-GE-700 1622 shp turboshaft engines, and has a speed of 163 mph (142 knots).
Elements of the U.S. Army Aviation UH-60A/l Blackhawk helicopter fleet will begin reaching their sevice life goal of 25 years in 2002. In order for the fleet to remain operationally effective through the time period 2025-2030 the aircraft will need to go through an inspection, refurbishment, and modernization process that will validate the structural integrity of the airframe, incorporate improvements in sub-systems so as to reduce maintenance requirements, and modernize the mission equipment and avionics to the levels compatible with Force XXI and Army After Next (AAN) demands.
A Service Life Extension Program (SLEP) is planned for the UH-60 beginning in FY99. The UH-60 modernization program will identify material requirements to effectively address known operational deficiencies to ensure the Black Hawk is equipped and capable of meeting battlefield requirements through the 2025-2030 timeframe. Primary modernization areas for consideration are: increased lift, advanced avionics (digital communications and navigation suites), enhanced aircraft survivability equipment (ASE), increased reliability and maintainability (R & M), airframe service life extension (SLEP), and reduced operations and support (O & S) costs. Suspense date for the approved Operational Requirements Document (ORD) is December 1998.
History: The UH-60A, first flown in October 1974, was developed as a result of the Utility Tactical Transport Aircraft System (UTTAS) program. The UTTAS was designed for troop transport, command and control, MedEvac, and reconnaissance, to replace the UH-1 Series "Huey" in the combat assault role. In August 1972, the U.S. Army selected the Sikorsky (model S-70) YUH-60A and the Boeing Vertol (model 237) YUH-61A (1974) as competitors in the Utility Tactical Transport Aircraft System (UTTAS) program. The Boeing Vertol YUH-61A had a four-bladed composite rotor, was powered by the same General Electric T700 engine as the Sikorsky YUH-60A, and could carry 11 troops. In December 1976 Sikorsky won the competition to produce the UH-60A, subsequently named the Black Hawk.
Variants: The Army began fielding the UH-60 in 1978. From 1978 until 1989 the Army procured UH-60A model aircraft. In October 1989, a power train upgrade resulted in a model designation change from UH-60A to UH-60L. The UH-60L version that provides 24 percent more power than the original 1970 UH-60A model. As of the end of FY97, the Army had procured 483 UH-60L models for a total UH-60 acquisition of 1,463 aircraft. The Army is in the fifth and final year of a multi-year procurement contract calling for the delivery of 60 aircraft per year.
UH-60L: In October 1989, the engines were upgraded to two General Electric T700-GE-701C 1890 shp turboshaft engines, and an improved durability gear box was added, resulting in a model designation change from UH-60A to UH-60L. The T700-GE-701C has better high altitude and hot weather performance, greater lifting capacity, and improved corrosion protection.
The UH-60 Firehawk is a Reseach and Development program to provide the UH-60 series helicopter with both a wartime and peacetime fire fighting capability by use of a detachable 1,000 gal. belly tank. Qualification issues include design and testing required to maintain the combat capabilities of the UH-60 Black Hawk and the safe flight envelope of the aircraft with the tank.
The EH-60A Electronic Countermeasures (ECM) variant has a unique external antenna designed to intercept and jam enemy communications. The EH-60E is powered by two General Electric T700-GE-700 1622 shp turboshaft engines.
The EH-60B version has a Stand-Off Target Acquisition System designed to detect the movement of enemy forces on the battlefield and relay the information to a ground station.
UH-60Q Medevac: The UH-60Q MEDEVAC helicopter provides significant enroute patient care enhancements. The UH-60Q provides a 6 patient litter system, on-board oxygen generation, and a medical suction system. UH-60Q is a UH-60A derivative and incorporates approximate UH-60A characteristics. It is simply the best in aeromedical evacuation. Building on the BLACK HAWK's heritage of saving lives in Grenada, Panama, Kuwait and Somalia, the UH-60Q delivers exceptional patient care, increased survivability, longer range, greater speed and added missions capability. For military combatants. War victims. Civilians injured in natural disasters. It has a state-of-the-art medical interior that can accomodate a crew of three and up to six acute care patients. The UH-60Q's leading-edge technology incorporates an improved environmental control system. Cardiac monitoring systems. Oxygen generation, distribution and suction systems. Airway management capability. Provision for stowing IV solutions. And an external electrical rescue hoist. And in addition to extensive immediate care, the UH-60Q can perform all weather terrain battlefield evacuation, combat search and rescue, hospital ship lifeline missions, deep operations support, forward surgical team transport, medical logistics resupply, medical personnel movement, patient regulating, disaster/humanitarian relief, and MAST/HELP state support.
The UH-60Q's medical interior can accomodate three to six acute care patients and their medical attendants. Ergonomic design has maximized the UH-60Q cabin space, placing sophisticated, life-saving instruments and equipment at the fingertips of the medical attendants. A unique platform design allows the interior to transport either six litter of seven ambulatory systems, oxygen distribution and suction systems, airway management capability, and provisions for stowing intravenous solutions. The interior also features these additional capabilities, essentical to providing the highest degree of patient care when every second counts:
- Oxygen Generating Systems
- NVG Compatible Lighting Throughout
- Environmental Control System
- Medical Equipment
- Patient Monitoring Equipment
- Neonatal Isolettes
Modernizing the Medical Evacuation (MEDEVAC) system is the Army Surgeon General's number one near term priority. The UH-60Q communications architecture provides situational awareness and digital communications and is expected to be the model for anticipated fleet-wide improvements to the UH-60. Other improvements include integrated Doppler/GPS, Personnel Locator System, NVG interior lighting, and FLIR.

AIM-120 AMRAAM
Function: The AIM-120 advanced medium-range air-to-air missile (AMRAAM) is a new generation air-to-air missile. It has an all-weather, beyond-visual-range capability and is scheduled to be operational beyond 2000. The AMRAAM is being procured for the Air Force, U.S. Navy and America's allies.
Description: The AMRAAM program improves the aerial combat capabilities of U.S. and allied aircraft to meet current and future threat of enemy air-to-air weapons. AMRAAM is compatible with the Air Force F-15, F-16 and developmental F-22; Navy F-14 D/D (R) and F/A-18 C/D; German F-4 and the British Sea Harrier aircraft.
AMRAAM is a follow-on to the AIM-7 Sparrow missile series. The missile is faster, smaller and lighter, and has improved capabilities against low-altitude targets. It incorporates active radar with an inertial reference unit and micro-computer system, which makes the missile less dependent upon the fire-control system of the aircraft. Once the missile closes on a target, its active radar guides it to intercept. This enables the pilot to aim and fire several missiles simultaneously at multiple targets. The pilot may then perform evasive maneuvers while the missiles guide themselves to their targets.
AMRAAM has three variants - AIM-120A/B/C -- operational on U.S. Air Force F-15 and F-16 aircraft.
History: The AMRAAM program completed its conceptual phase in February 1979 when the U.S. Air Force selected two of five competing contractors, Hughes Aircraft Co. and Raytheon Co., to continue into the validation phase.
During the 33-month validation phase the contractors continued missile development by building actual hardware to demonstrate their technological concepts. The program phase concluded in December 1981 after both contractors demonstrated that their flight-test missiles could satisfy Air Force and Navy requirements. The Air Force competitively selected Hughes Aircraft Co.'s Missile System Group, Canoga Park, CA, as the full-scale developer.
During the full-scale development phase, Hughes Aircraft Co. completed missile development and Raytheon was selected as a follower producer. A production contract to both vendors was awarded in 1987. More than 200 of the test missiles were launched during flight tests at Eglin AFB, FL; White Sands Missile Range, NM; and Point Mugu, CA. AMRAAM is combat tested, scoring two kills during Operation Southern Watch, and one kill in Bosnia.

a. Decoration (regular size): MIL-D-3943/22. NSN for decoration set is 8455-00-269-5749. NSN for replacement medal is 8455-00-246-3829.
b. Decoration (miniature size): MIL-D-3943/22. NSN 8455-00-996-5004.
c. Ribbon: MIL-R-11589/18. NSN 8455-00-252-9915.
d. Lapel Button: MIL-R-11484/16. NSN 8455-00-265-4889.
5. Background: a. General George C. Marshall, in a memorandum to President Roosevelt dated February 3, 1944, wrote: "The fact that the ground troops, Infantry in particular, lead miserable lives of extreme discomfort and are the ones who must close in personal combat with the enemy, makes the maintenance of their morale of great importance. The award of the Air Medal have had an adverse reaction on the ground troops, particularly the Infantry Riflemen who are now suffering the heaviest losses, air or ground, in the Army, and enduring the greatest hardships." The Air Medal had been adopted two years earlier to raise airmen?s morale.
b. President Roosevelt authorized the Bronze Star Medal by Executive Order 9419 dated 4 February 1944, retroactive to 7 December 1941. This authorization was announced in War Department Bulletin No. 3, dated 10 February 1944. The Executive Order was amended by President Kennedy, per Executive Order 11046 dated 24 August 1962, to expand the authorization to include those serving with friendly forces.
c. As a result of a study conducted in 1947, the policy was implemented that authorized the retroactive award of the Bronze Star Medal to soldiers who had received the Combat Infantryman Badge or the Combat Medical Badge during World War II. The basis for doing this was that the badges were awarded only to soldiers who had borne the hardships which resulted in General Marshall?s support of the Bronze Star Medal. Both badges required a recommendation by the commander and a citation in orders.
d. Order of precedence and wear of decorations is contained in Army Regulation 670-1. Policy for awards, approving authority, supply, and issue of decorations is contained in AR 600-8-22.

Su-47 (S-37) Berkut
Function: The Su-47 (initially known as the S-37) Berkut (Golden Eagle) is a testbed for developing technologies for the next generation of aircraft.
Description: The basic dimensions and weight of the Su-47 "Berkut" are similar to those of Su-37, although they are different aircraft, and the tail, nose and canopy are similar to those of the Su-35. The first two prototypes of this aircraft were evidently designated the S-32, and the S-37 designation was previously applied to an unrelated fighter project for a smaller delta wing single aircraft that was cancelled due to lack of funding.
The Su-47 features forward-swept wings, which promises a range of benefits in aerodynamics at subsonic speeds and at high angles of attack. The forward-swept wing, which enables the aircraft to increase its range and its manoeuvrability at high altitude, makes extensive use of composite materials. The aircraft has large canards mounted on the intake side, close to the leading edge of the wing. The vertical stabilizers are canted slightly outward [not inward, as previously believed], and two large auxiliary intake doors are visible on the center fuselage section. It is unclear which engines are used on this aircraft. The two powerplants are at the moment D-30F6 turbojets which are normaly used at the MiG-31M, while the second prototype uses the Ljulka AL-37FU turbojet with thrust vectoring. The Su-47 is an experimental program for developing fifth-generation technologies.
The Su-47 is a better performer at high angles of attack in post-stall manoeuvring much needed in close-in dogfight. Having the edge in manoeuvring, the Su-47 is clearly catching up in stealth with US and European new-generation fighters. However even with its internal weapon bay and RAM coating, the new Sukhoi is a very different concept than F-22. The heavy accent on RAM rather than radar absorbing structures (RAS) is obvious. The major components of radar stealth -- RAM coatings and surface quality -- are subject to the production and maintenance tolerance as it was shown by USAF F-117 and B-2 operational experience. Untightened screws, scratches or unfastened access panels were known to greatly deteriorate the RCS of the aircraft, reducing the engineering efforts put into aircraft design. It remains to be seen how Sukhoi will overcome the looser production standards of the Russian aircraft plans.

Charleston, 28 June 1776
In June 1776 British Admiral Peter Parker 'a fleet, loaded with troops commanded by General Henry Clinton, made an appearance off Charleston, South Carolina. The city, feverishly preparing for an attack, had partially completed Fort Sullivan, Charleston's key defense position. The 30-gun fort on Sullivan's Island was hastily constructed from the moat abundant materials available, palmetto logs and sand. The garrison, commanded by Colonel William Moultrie, contained over 400 men including 22 artillerists and the 2d South Carolina Provincial Regiment.
Because of a sand bar the British delayed their attack on Charleston until 28 June 1775 while they lightened ship. Clinton's 2,000 British soldiers, landing on adjacent Long Island, were unable to cross an estuary to join in the attack. The fleet began its bombardment at a range of about 400 yards. Low on powder, Moultrie directed his men to fire slowly and accurately in reply.
During the engagement a shell struck the flagpole, and the blue South Carolina banner fell outside the fort. Sergeant William Jasper retrieved it and, oblivious to British fire, secured the flag to a makeshift staff.
The falling shells, absorbed by the soft palmetto loge and sand, caused little damage to the fort and few casualties. Even shells that did enter the fort buried themselves in the swampy parade ground. The wooden frigates on the other hand were riddled with shot. One explosion blew away Sir Peter Parker's breeches.
Finally, after more than ten hours of firing, the British fleet withdrew and several weeks later sailed for New York. For three years following the defeat at Charleston the British were to leave the South unmolested and the Southern Tories, who were undoubtedly numerous, without succor.
