SSN671 - USS Narwhal Fast
Function: One-of-a-kind prototype built off of the Sturgeon class SSN design.
History: Literally in a class by herself, the USS Narwhal was the only submarine of the Sturgeon class to be built with a prototype natural circulation nuclear reactor. Because the natural circulation powerplant did not need noise generating pumps to circulate the reactor coolant, at the time of her construction the Narwhal was the quietest submarine in the world. Coupled with the most advanced sensors and combat systems available, the Narwhal was without peer in the performance of her duties. Given her superior performance, Narwhal was ideally suited to perform intelligence gathering eavesdropping missions; during the course of her career Narwhal deployed overseas seventeen times and was awarded the Navy Unit Commendation, three Meritorious Unit Commendations, five Battle Efficiency "E" awards, four Engineering "E" awards, the Antisubmarine Warfare "A", the Communications "C", and the Supply "E" awards.

SSN688 - Los Angeles Clas
Function: Nuclear powered Fast Attack submarine.
History: Deployed on November 13, 1976, the Los Angeles (SSN688) fast attack submarine marked a technological leap forward in submarine design. Built from the screw forward as a dedicated antisubmarine warfare (ASW) platform, the Los Angeles class submarines were designed to guard American Carrier Battle Groups by hunting Soviet submarines and anti-surface warfare (ASUW) capitol ships like the Kirov class BCGN. The Los Angeles submarines were faster, quieter, carried more sophisticated sensors and possessed better weapons than any other submarine in existence. In addition to their primary function as offensive ASW weapons the 688 boats perform a number of additional duties to include sub surface precision land attack strikes (using tube launched Tomahawk cruise missiles), intelligence gathering, mine warfare, and special operations support (SEAL deployment and recovery). In fact, their performance was so revolutionary that beginning with USS Providence (SSN719) the hull was lengthened to accommodate 12 vertical launch system (VLS) tubes to allow the submarines to launch Tomahawk land attack cruise missiles. Nearing the end of their 30-year lives, the Los Angeles class submarines are slowly being replaced by the Improved Los Angeles (San Juan SSN751), the Seawolf (SSN21) and ultimately by the Virginia class (SSN774).

SSN688(I) - San Juan Clas
Function: Nuclear powered Fast Attack submarine.
History: The Los Angeles class SSN design proved to be so effective that as time progressed and technological improvements were made to the submarine's systems, rather than build a completely new class of boat it was decided to reuse the Los Angeles design, but fitted with newer, more advanced systems. Based on research and development studies, performed in part by USS Memphis (SSN691) which had been specifically modified during refit to serve as a technology test bed, several major improvements were made to the basic Los Angeles design. In addition to internal upgrades to improve the submarine's sensors and to make it quieter, the hull was also modified to increase submerged speed. Furthermore, by strengthening the sail and moving the forward dive planes from the sail to the bow, the San Juan boats have a true "under ice" capability. The Improved Los Angeles (or San Juan class) submarines currently fill the role of America's front line fast attack submarine, surpassing the Los Angeles class in all respects, and will continue to serve until replaced by either the Seawolf class (SSN21) or the Virginia class (SSN774).

SSGN - Guided Missile Sub
Function: SSGN Guided Missile Submarines are nuclear-powered submarines armed with tactical missiles and the ability to transport and support special operations forces.
Entered Navy: Beginning 2003 / 2004.
Description: Four Ohio-class Trident submarines that were previously scheduled for inactivation during Fiscal Years 2003 and 2004 are being converted to guided missile submarines (SSGN) over a five-year period ending in 2008. The primary missions of the SSGN will be land attack and Special Operations Forces (SOF) insertion and support. Secondary missions will be the traditional attack submarine missions of intelligence, surveillance and reconnaissance (ISR), battle space preparation, and sea control.
These ships will be armed with up to 154 Tomahawk? or Tactical Tomahawk? land attack missiles. They will have the ability to carry and support a team of 66 SOF personnel for up to 90 days as compared to 15 days for a SOF outfitted fast attack submarine (SSN). Clandestine insertion and retrieval of these Special Operations Forces will be enhanced by the ability to host dual dry deck shelters and/or Advanced Seal Delivery System. Each SSGN will be able to conduct a variety of peace-time, conventional deterrent, and combat operations all within the same deployment.
USS Ohio (SSBN 726) entered the conversion yard on 15 November 2002. On 14 January 2003, USS Florida (SSBN 728) became the first Ohio-class submarine to launcha cruise missile. The launch was made from underwater in the Gulf of Mexico.

LSV-2: Large Scale Vehicl
Function: The world's largest unmanned autonomous submarine. LSV 2 Cutthroat will offer the capability to conduct a wide variety of studies dramatically improving the acoustic and operational performance of future submarines.
Entered Navy: 2001.
Description: LSV 2 Cutthroat will provide submarine design engineers a platform to test advanced submarine technologies.
Cutthroat, a 205-ton, large scale submarine test vehicle, will be used to affordably explore and test emerging technologies and to conduct physics-based experiments. Specific emphasis will be on stealth, hydrodynamics, hydroacoustics and propulsion designs to permit technology insertion into current and future submarines.
The LSV 2 will provide the capability to develop and evaluate the effectiveness of new technologies that will result in major improvements in performance for the U.S. Navy's new attack submarine, USS Virginia (SSN 774). The LSV 2 is being designed and built by an industry team from Newport News Shipbuilding and General Dynamics/Electric Boat Company under contract from Naval Sea Systems Command (NAVSEA).
After delivery in 2001, LSV 2 will operate on Lake Pend Oreille at the Acoustic Research Detachment in Bayview, Idaho, the Navy's laboratory for demonstrating submarine stealth technology. The facility is operated by the Naval Surface Warfare Center's Carderock Division.
Cutthroat, named after a native Idaho trout, was named in 1997 after a selection process by nearby Athol Elementary School. The Navy asked the school to decide on a name from a list of indigenous Idaho fish. Many of these students attended the keel-laying in October 1997 and signed their names on the hull during the November 2000 ceremony.
Cutthroat is similar to Kokanee (LSV-1), but more advanced. Enhancements include a larger overall scale ? 29 percent, vice 25 percent for Kokanee ? which will improve the fidelity of test data to full-scale results. Cutthroat is designed to be more modular than Kokanee, so that major modifications, including radical hull changes, can be made with less impact to other systems onboard the vessel. Another advantage is an increase in ODAS capability. The Cutthroat ODAS will have twice as many data channels recorded as Kokanee at delivery ? 512, vice 256 ? and this is upgradable to 1,536 recorded channels. The Cutthroat ODAS converts the data from analog to digital form and processes the data digitally. In Cutthroat, data recording can be configured electronically under computer control, whereas Kokanee uses a patch panel. Cutthroat is equipped with a 3,000 horsepower permanent-magnet, radial-gap electric propulsion motor, provided to the Navy under a unique partnership agreement with General Dynamics Electric Boat, the owner of the technology. This motor is easily upgradable to 6,000 horsepower. Other order-of-magnitude improvements were engineered into the guidance, navigation, control, and propulsion systems, including the addition of torque sensors and other sensors of mechanical data for better reconstruction of the scenario.

Far East Air Forces
The Far East Air Forces shoulder patch was approved by the QMG on April 230h, 1945. The colors are those of the United States Army Air Forces. The wings and the star with the red disc in the center indicate that the organization is an Army Air Forces unit, while the Philippine Sun and the Southern Cross represent the location of the organization.
The Far East Air Forces (FEAF) was activated in Brisbane, Australia on the 3rd of August, 1944. The mission of the FEAF was for providing command control over the United States Air Forces units in the Southwest Pacific Area. The Commander of the FEAF was General MacArthur's chief air officer, Major General George Kenney whom orginized the remnants of Air Force units in the command into the Fifth Air Force in 1942. When the Thirteeth Air Force moved into the area to join in the New Guinea fighting, a unified command was needed to coordinate the efforts of the two Air Forcees, and so the FEAF was established. Operating from an advanced base in New Guinea and later from the Philippines, the Headquarters provided brilliant and innovative command leadership through much of the hard fighting in the Southwest Pacific island area and during the Battle for Philippines. Although the Command's mission included flying strategic and tactical missions, the main objective of FEAF was to destroy the Japanese Air Forces, and the aircrews assigned to FEAF did just that. After Okinawa was added to General MacArthur's area of responsibility in July of 1945, the Seventh Air Force was also assigned to FEAF. When the United States occupation forces arrived in Japan in August of 1945, an advanced Headquarters for FEAF comprised part of the first group that landed, and FEAF established its Headquarters i Tokyo. The FEAF was redesignated the Pacific Air Command on December 6th, 1945, and eventually became the Pacific Air Forces in July of 1947. It should be noted that the lineage of the original Far East Air Forces that was created in October of 1941 went to the Fifth Air Force when it was formally established in September of 1942. On Januaty 19th, 1946, a letter from the QMG redesignated the FEAF shoulder patch for the Pacific Air Command, United States Army.

Air Force Air Transport C
The Air Force Air Transport Command (AFATC) shoulder patch was changed from the design previously used by its parent unit the Air Force Ferrying Command. This modified patch would be of the same general design but would be silver, instead of gold, and the morse code would read "AFATC" instead of the "AFFC". The design of the shoulder patch suggests a stylized aircraft being ferried from east to west over a portion of the globe. The design is based on a Presidential Directive from Franklin D. Roosevelt (as Commander in Chief) ordering that ircraft be ferried for delivery to the British "with the greatest possible speed." It should be noted that the short and long red and blue lines extending from the globe to the tip of the wing form the Morse code letters and were part of the originally approved design. Although the QMG made no mention of the new "cloth" insignia just the metal insignia, it is believed that these patches were worn by local approval only.
The AFATC was established on June 20th, 1942, as a successor Command to the SAir Forces Ferrying Command with Headquarters in Washington, D.C. The Ferrying Division of AFATC took charge of all ferrying operations and continured this missiion of ferrying aircraft to foreign and domestic destinations and often delivered 8,000 aircraft monthly. AFATC was also made responsible for transporting all War Department personnel, material, and mail (escept for areas served by Troop Carrier Units). In addition, AFATC was given the control, operation, and maintenance for all air route facilities and establishments in effect, the AFATC became "an agency in which the War Department had centered a;ll responsibbility for the development of air transport." To accomplish its mission, AFATC established a network of over 200 bases along 100,000 miles of overseas routes and 35,000 miles of domestic routes. Aircraft from civilian carriers were contracted (Air Carrier Contracat Personnel)) and added to the Command, ad passenger service became a major function of AFATC. With the addition of overseas wings to the Command, the prompt delivery of cargo to combat areas in any theater of operations became "one of the most significant developments of the war." While statistics do not indicat4 how many battles were won by the prompt delivery of priority cargo to the battlefront by the Air Transport Command, history reveals that no battle was ever lost because of a lack of support from the men of this fine unit.

Yorktown, 14 October 1781
In the summer of 1781, ending a campaign in Virginia, Cornwallis took post at Yorktown with a force of about 8,000 men. Washington, meanwhile, guarding Clinton's main British force in New York, was joined in April by 4,000 French troops under the Comte de Rochambeau. On 14 August he learned that French Admiral De Grasse, with a powerful fleet, was sailing from the West Indies to the Chesapeake Bay. In the hope of surrounding Cornwallis by land and sea, Washington hurried southward with the main portion of the Franco-American Army, leaving only a small force to guard Clinton in New York.
The plan worked remarkably well. De Grasse arrived in the Chesapeake on 30 August, landed additional French troops, and fought an indecisive battle with the British fleet, but at its end remained in firm control of the bay as the Allied armies arrived. On 28 September these armies began siege operations, using the traditional European system of approaches by parallel trenches. In order to complete the second parallel, Washington ordered the seizure of two British redoubts near the York River. The French were assigned the first, Redoubt No. 9, and the American Light Infantry under Lt. Col. Alexander Hamilton the second, Redoubt No. 10. On the evening of 14 October, as covering fire of shot and shell arched overhead, the Americans and French moved forward. The Americans, with unloaded muskets and fixed bayonets, did not wait for sappers to clear away the abatis, as the French did, but climbed over and through the obstructions. Within ten minutes the garrison of Redoubt No. 10! was overwhelmed. The French also met with success but suffered heavier losses.
After a vain attempt to escape across the York, Cornwallis surrendered his entire force on 19 October 1781, an event that virtually assured American independence, although the final treaty of peace was not signed until 3 September 1783.

XM8
The XM8 Future Combat Rifle is intended to replace existing M4 Carbines and select 5.56mm x45 weapons in the US Army arsenal beginning as early as the fourth quarter of FY05.
In October 2002 ATK (Alliant Techsystems) was awarded a $5 million contract modification from the U.S. Army Armament Research, Development, and Engineering Center (ARDEC), Picatinny, N.J., to develop the new XM8 Lightweight Assault Rifle. ATK Integrated Defense, Plymouth, Minn., and teammate Heckler and Koch, Oberndorf, Germany, will support the rapid development program, which will investigate the potential of the XM8 as the lightweight assault rifle for the Army's Objective Force.
The XM8 will be based on the kinetic energy weapon that is part of the XM29 next-generation infantry weapon system (formerly the Objective Individual Combat Weapon) currently under development by ATK Integrated Defense. The kinetic energy weapon, which fires 5.56mm ammunition, will provide maximum commonality in components and logistics with the XM29 system.
The XM8 will provide lethality performance comparable to the currently fielded M4 carbine rifle, while weighing 20 percent less than the M4 because of advanced technologies developed for the XM29 program.
The XM8 Lightweight Assault Rifle will reduce the 21st century soldier's load and increase his mobility - two very important aims of the Army's Objective Force Warrior and Land Warrior initiatives. The progress made to reduce weight and improve performance on the XM29 program is key to the decision on accelerating the development of the XM8, which is integrated with the Army's efforts to transform to a more lethal and rapidly deployed fighting force as part of its Objective Force.
ATK Integrated Defense is the system integrator on the XM29 program. Teammates on the program are Heckler and Koch, weapon development; ATK Ammunition Systems, Arden Hills, Minn., ammunition development; Brashear LP, Pittsburgh, Pa., integrated full solution fire control; and Omega, Columbus, Ga., training systems.
The XM8 is a true family of weapons with different barrel lengths designed to address all the needs of an infantry squad. The standard model is expected to be lighter than the M4 carbine and no larger in size. There?s also a sharpshooter version for increased range; a compact version for cramped quarters; and an auto-rifle version for a squad-automatic weapon. The XM8 family has a 9-inch compact, 12.5-inch carbine and a 20-inch sharpshooter and automatic rifle. The 12.5-inch carbine is 6.4 pounds with an objective of 5.7 pounds and is 33 inches with its adjustable stock extended. The M-16 A2 is 39.63 inches long and 8.79 pounds with a 30-round magazine.
Internally, the XM8 uses a rotary locking bolt system that functions and fieldstrips like those used in the M-16 rifle and M-4 carbine, according to the XM8 manufacturer?s ? Heckler & Koch ? Website. The bolt is powered by a unique gas operating system with a user-removable gas piston and pusher rod to operate the mechanism. Unlike the current M-4 and M-16 direct gas system with gas tube, the XM8 gas system does not introduce propellant gases and carbon back into the weapon?s receiver during firing.
While the XM8 was not exposed to battlefield conditions, it?s still a feat the current service rifle hasn?t come close to rivaling, said Rich Audette, deputy project manager for PM Soldier Weapons. During their Oct. 20-23 2003 trip to Germany, the weapons experts said they were impressed after watching Heckler & Koch engineers fire four high-capacity magazines, with 100 rounds a piece, in less than five minutes.
This improved reliability can be credited to differences in the XM8?s operating system from the one in the M16. For instance, a thin gas tube runs almost the entire length of the barrel in all of the M16 variants. When the weapon is fired, the gases travel back down the tube into the chamber and push the bolt back to eject the shell casing and chamber a new round. The XM8?s gas system instead is connected to a mechanical operating rod, which pushes back the bolt to eject the casing and chamber the new round each time the weapon is fired. So there?s no carbon residue constantly being blown back into the chamber, reducing the need to clean the weapon as often. You don?t get gases blowing back into the chamber that have contaminates in them. The XM8 also has a much tighter seal between the bolt and the ejection port, which should cut down on the amount of debris that can blow into the weapon when the ejection port?s dust cover is open.
The XM8 is part of the Army?s effort to perfect an over-and-under style weapon, known as the XM29, developed by Alliant Techsystems and H&K. It fires special air-bursting projectiles and standard 5.56mm ammunition. But the XM29 still is too heavy and unwieldy for Army requirements. Instead of scrapping the XM29, the Army decided to perfect each of XM29?s components separately, so soldiers can take advantage of new technology sooner. The parts would be brought back together when lighter materials become available. The XM8 is one of those components.
From December 2003 through late May 2004, soldiers got a chance to fire the prototypes in desert, tropical and arctic environments. A limited-user test then was conducted, possibly at Fort Campbell, Ky., where soldiers test the prototypes for about three weeks while training in offensive and defensive scenarios. Improvements will be made based on soldier and test feedback before the final three-months of operational tests, which are scheduled to begin in fall 2004. The final decision will be up to the Army?s senior leadership, but weapons officials said they were confident the XM8 weapon system will be adopted. If all goes well, the XM8 could be ready for fielding by late summer 2005.
Beginning life as the 5.56mm KE (kinetic energy) component of the 20mm air-bursting XM29 Objective Individual Combat Weapon (OICW), the XM8 Lightweight Modular Carbine System represents the state-of-the-art in 5.56x45mm NATO assault rifles. Developed by the US Army?s office of Project Manager for Soldier Weapons located at Picatinny Arsenal, New Jersey in close conjunction with the US Army Infantry Center, the XM8 Future Combat Rifle is intended to replace existing M4 Carbines and select 5.56mm x45 weapons in the US Army arsenal beginning as early as the fourth quarter of FY05. Once adopted, the M8 Carbine will replace the aging M16/M4 family of weapons, which have been in service for nearly four decades, longer than any previous US service rifle. The M8 Carbine will be up to 20% lighter than a comparably equipped M4 Carbine MWS and yet offer additional features and performance unavailable currently in any assault rifle in the world.
As a direct development of the separable OICW (XM29) KE or Kinetic Energy module, the M8 Carbine will share a high degree of common parts and training and maintenance procedures to lessen the required support for the ?family? of XM8 weapons. Being developed are four XM8 variants, which include a baseline carbine, a sharpshooter variant, an automatic rifle variant, and the ultra-compact carbine variant. A unique feature of the XM8 modular weapon system is the ability to easily and quickly reconfigure the weapon from one variant to the other to meet changing mission requirements, to include caliber conversion.
This modularity includes the exchange of interchangeable assembly groups such as the barrel, handguard, lower receiver, buttstock modules and sighting system with removable carrying handle. In addition and in parallel, the new XM320 quick detachable single-shot 40mm grenade launcher with side-opening breech and LSS lightweight 12 gauge shotgun module can be easily added to the XM8 by the user in the field without tools. The unique buttstock system allows the operator exchange buttstocks without tools from the standard collapsible multi-position version, to an optional buttcap for maximum portability or an optional folding or sniper buttstock with adjustable cheekpiece for special applications. Internally the XM8 employs a combat-proven robust rotary locking bolt system that functions and fieldstrips like that used in the current M16 rifle and M4 carbine. However this bolt is powered by a unique gas operating system that employs a user removable gas piston and pusher rod to operate the mechanism. Unlike the current M4/M16 direct gas system with gas tube, the XM8 gas system does not introduce propellant gases and the associated carbon fouling back into the weapon?s receiver during firing. This greatly increases the reliability of the XM8 while at same time reducing operator cleaning time by as much as 70%. This system also allows the weapon to fire more than 15,000 rounds without lubrication or cleaning in even the worst operational environments. A cold hammer forged barrel will guarantee a minimum of 20,000 rounds service life and ultimate operator safety in the event of an obstructed bore occurrence.
The XM8 has fully ambidextrous operating controls to include a centrally located charging handle that doubles as an ambidextrous forward assist when required, ambidextrous magazine release, bolt catch, safety/selector lever with semi and full automatic modes of fire and release lever for the multiple position collapsible buttstock. The operating controls allow the operator to keep the firing hand on the pistol grip and the weapon in the firing position at all times while the non-firing hand actuates the charging handle and magazine during loading and clearing. Major components of the weapon are produced from high-strength fiber reinforced polymer materials that can be molded in almost any color to include OD green, desert tan, arctic white, urban blue, brown and basic black. Surfaces on the XM8 that interface with the operator are fitted with non-slip materials to increase comfort and operator retention. The XM8 uses 10 or 30-round semi-transparent box magazines and high-reliability 100-round drum magazines for sustained fire applications.
Special integral flush mounted attachment points are located on the handguard and receiver to allow the quick attachment of targeting devices. Unlike MIL-STD-1913 rails, the XM8 attachment points do not add additional weight, bulk and cost to the host weapon, and will accept MIL-STD-1913 adapters to allow for the use of current in-service accessories. The attachment points for the standard multi-function integrated red-dot sight allow multiple mounting positions and insure 100% zero retention even after the sight is removed and remounted. The battery powered XM8 sight includes the latest technology in a red dot close combat optic, IR laser aimer and laser illuminator with back-up etched reticle with capability exceeding that of the current M68-CCO, AN/PEQ-2 and AN/PAQ-4. This sight will be factory zeroed on the weapon when it is delivered and does not require constant rezeroing in the field like current rail-mounted targeting devices. The XM8 will be fully compatible with future Land Warrior technology and components.
The US XM8 Carbine is being designed at the HK Defense design center in Sterling, Virginia and will be produced and assembled in the United States at the new Heckler & Koch manufacturing plant located in Columbus, Georgia, adjacent to Fort Benning. The unit cost of the XM8 will be less than that of the current M4 Carbine and will guarantee the American war fighter uncompromising performance far exceeding that of current in-service M4 Carbines.
