TheBoeing MH-6M Little Bird (nicknamed theKiller Egg) and itsattack variant, the AH-6, are lighthelicopters used forspecial operations in theUnited States Army. Originally based on a modifiedOH-6A, it was later based on theMD 500E, with a single five-bladed mainrotor. The newest version, theMH-6M, is based on theMD 530F and has a single, six-bladed main rotor and four-bladed tail rotor.
The OH-6 was started in 1960, when the US Army issued Technical Specification 153 for aLight Observation Helicopter (LOH) that could perform personnel transport, escort andattack missions,casualty evacuation, and observation. Twelve companies took part in the competition andHughes Tool Company's Aircraft Division submitted theModel 369. Two designs, those submitted byFairchild-Hiller andBell, were selected as finalists by the Army-Navy design competition board, but the Army later included the helicopter from Hughes as well.[citation needed]
The first Model 369 prototype flew on 27 February 1963. Originally designated theYHO-6A under the army's designation system, the aircraft was redesignated theYOH-6A under theDepartment of Defense's new joint system in 1962. Five prototypes were built, each fitted with a 252 shp (188 kW)AllisonT63-A-5A engine,[1] and delivered to the US Army atFort Rucker,Alabama to compete against the other 10 prototype aircraft submitted by Bell and Fairchild-Hiller. In the end, Hughes won the competition[2] and the Army awarded a contract for production in May 1965. The initial order was for 714 aircraft, but that was later increased to 1,300 with an option to buy another 114. Seventy helicopters were built in the first month.[citation needed]
This agile, unarmed helicopter is outfitted with outboard "benches" designed to ferry up to 3 operators on each side. There is also agunship variant, the AH-6. Painted black for nighttime operations, this small aircraft can conduct rapid insertions and extractions ofspecial operations forces into areas its larger counterpart, theMH-60 Black Hawk can't.[citation needed]

After the April 1980 failure ofOperation Eagle Claw, in whichMarine pilots andNavy helicopters were used, it was determined that the US Army lacked aircraft and crews who were trained and prepared to perform special operations missions. To remedy this shortcoming, the Army began developing a special aviation task force to prepare for the next attempt to rescue the hostages:Operation Credible Sport.
The United States Army160th Special Operations Aviation Regiment (Airborne), also known as Night Stalkers, is a special operations force that provides helicopter aviation support for general purpose forces and special operations forces. Its missions have included attack, assault, andreconnaissance, and are usually conducted at night, at high speeds, low altitudes, and on short notice.
The architects of the task force identified the need for a small helicopter that could land in the most restrictive locations and could be easily transported on Air Force airlifters. They chose the OH-6A scout helicopter, and it became known as theLittle Bird compared to the other aircraft in the task force, the UH-60A and the CH-47C. As a separate part of the project, armed OH-6As were being developed at Fort Rucker, Alabama.
The pilots selected to fly the OH-6A helicopters came from the 229th Attack Helicopter Battalion and were sent to the Mississippi Army National Guard's Army Aviation Support Facility (AASF) atGulfport,Mississippi, for two weeks of qualification training in the aircraft. When the training was completed,C-141 aircraft transported the aircraft and crews toFort Huachuca, Arizona, for two weeks of mission training. The mission training consisted of loading ontoC-130 transport aircraft which would then transport them to forward staging areas over routes as long as 1,000 nautical miles (1,900 km). The armed OH-6 aircraft from Fort Rucker joined the training program in the fall of 1980.
Operation Credible Sport was a joint project of the U.S. military in the second half of 1980 to prepare for a second rescue attempt of thehostages held in Iran. It was canceled after the hostages were released on 20 January 1981 and, for a short while, it looked as if the task force would be disbanded and the personnel returned to their former units. However, the Army decided that it would be more prudent to keep the unit. The task force, which had been designated Task Force 158, was soon formed into the160th Special Operations Aviation Regiment. The OH-6A helicopters used for transporting personnel became the MH-6 aircraft of the Light Assault Company and the armed OH-6As became the AH-6 aircraft of the Light Attack Company.
The OH-6s of 160th SOAR saw overt combat action for the first time inGrenada duringOperation Urgent Fury on the Oct. 25, 1983. On D-Day, six MH-6 and two AH-6s were flown to theEastern Caribbean island fromPope Air Force Base inNorth Carolina in the bellies of four Air ForceC-130s. In addition to the helicopter air crews, the aircraft also carried a company ofUS Army Rangers and aDelta Force squadron, units that were also part of the American assault forces.[3] By the time the aircraft arrived over the island, other Rangers, flying separately from the US, had parachuted onto a nearly finished runway on the island's southwestern coast. When the air-dropped Rangers secured the runway, the four C-130s landed and unloaded. The two AH-6s set off for the capital city ofSt. George's to attack Fort Rupert, the permanent Grenadian military headquarters. The “Little Birds” found air defenses around the capital to be too formidable and they returned to the airport within 10 minutes. (This action appears to have given rise to later erroneous published speculation that an OH-6 was shot down on D-Day)[4] A planned MH-6 assault by the Ranger/Delta force on Fort Rupert (also known as Fort George) was cancelled because of the stiff antiaircraft resistance. However, it did participate in other unscripted support tasks, including ferrying wounded servicemen to medical facilities on Navy ships offshore and a search and rescue mission to a Black Hawk helicopter crash site.[3]
None of these aircraft were listed in the public inventory of US military at the time.[4] The existence of the secret aviation unit became widely known in the aftermath of the invasion, as OH-6s helicopters were photographed and filmed in action by civilians onlookers.[3]
The CIA also deployed two highly modified, "silent"Hughes 500D helicopters to nearby Barbados in advance of the invasion. They were offered to the Pentagon's invasion commanders for clandestine reconnaissance purposes, but were not used by the military over Grenada during Urgent Fury.[5]
By 1983, 160th SOAR and its helicopters were heavily committed to supporting theContras, a United States-subsidized military force. Specially adapted unmarkedHughes 500D helicopters from the CIA Seaspray unit based inFort Eustis also took part in this task.[6]
MH-6s were based inPalmerola Air Base,Honduras, and flew missions intoNicaragua. The unit members wore civilian clothes, flew by night, and were instructed to destroy their aircraft if they were forced down.
On 24 July 1987, a Kuwaitioil tanker,reflagged asBridgeton and escorted by U.S. Navy warships, struck amine in thePersian Gulf. It became apparent that more thanescort ships would be required to guard merchant ships. The U.S. military deployed the MH-6 and AH-6 aircraft from the 160th Special Operations Aviation Regiment (SOAR) to provide surveillance and patrols in cooperation with other U.S. special operations units inOperation Prime Chance.
Two MH-6 and four AH-6 aircraft were initially deployed and designated as Detachment 160 Aviation Group (DET 160 AVGP). The MH-6 aircraft carriedForward Looking Infra-Red (FLIR) and a videotape system which gave them excellent ability to detect and identify targets, then direct the armed AH-6s. The AH-6 helicopters were armed with7.62 miniguns and2.75-inch rockets. Initially, the aircraft patrolled in teams (call sign "SEABAT") that waited for U.S. NavySH-2s to direct them to the targets. Later, to preserve the aircraft and crews from fatigue and wear, the SEABAT teams remained on the ship's deck until a contact was identified.
At 10 pm on 21 September 1987, the captain ofUSS Jarrett launched a SEABAT team (a MH-6 and two AH-6s) to check out reports of Iranian minelaying. The team foundIran Ajr, anamphibious landing ship equipped with minelaying racks. The MH-6 confirmed thatIran Ajr was laying mines, the AH-6s opened fire, causing the crew to abandon ship. The vessel was subsequently boarded and captured.
On the night of 8 October 1987, an Iranian Revolutionary Guard CorpsBoghammar and twoBoston Whaler boats were detected by an SH-2. A SEABAT team was launched fromUSS Ford (FFG-54), and as the MH-6 drew near to investigate, the Boghammar opened fire, the first of a series of engagements by both AH-6s and the MH-6 (recently armed with a minigun). The Boghammar launched twoStinger missiles at the helicopters, but eventually all three boats were sunk.
For the remainder of the operation,barges, set up as mobile sea bases (MSB), would facilitate the operation of the special operations forces.Hercules andWimbrown VII were leased to provide these bases and the SEABAT teams began operating from the barges.
In early 1988, it was decided that modified U.S. ArmyOH-58D helicopters, fitted with weapons, would replace the SEABAT teams. On 24 February 1988, a team of twoAHIP helicopters replaced the SEABAT team on the Wimbrown VII but it would be several months (June 1988) before the SEABAT team aboard the barge Hercules would be relieved by another AHIP detachment.[6]
On 17 December 1989, 9 MH-6s, 11 AH-6G/Js, 19 UH/MH-60As were flown by Air ForceC-5 Galaxy airlifters toHoward AFB's Hangar 3. After dark, on 19 December, the aircraft were rolled out to prepare forOperation Just Cause.
Before the main invasion force arrived inPanama City, Panama, two MH-6s supported by two AH-6s landed atTorrijos-Tocumen Airport to insert a beacon and combat controllers. Four other AH-6s conducted pre-assault attacks on thePanamanian Defense Force (PDF) Headquarters,La Comandancia, adjoining the heavily populatedEl Chorrillo neighborhood in downtownPanama City. One of the AH-6s was damaged by ground fire and crashlanded in the Comandancia compound. The two pilots, pinned down bysmall-arms fire for two hours, eventually made their way back to friendly forces, taking a PDF soldier prisoner along the way.
Other AH-6s escorted MH-6s on a rooftop rescue operation conducted atCárcel Modelo, a prison adjacent to La Comandancia. InOperation Acid Gambit, the aircraft approached the prison. Under fire from a nearby apartment house, the Little Birds landed on the roof, dropped off the rescue team, and lifted off. Upon their return, heavy smoke made it tough to find the roof and the helicopters took heavy fire from acellblock about 50 to 60 feet (18 m) from the landing site. Maj. Richard Bowman, acopilot, took a round in the elbow. His pilot took over the controls and landed the aircraft. The aircraft picked up the rescue personnel and headed back toward Howard AFB, but one MH-6 lost power as it left the roof, and crashed in the street below with minor injuries to the passengers, who were helped from the crash site by USinfantry soldiers.
Elsewhere, four AH-6s provided fire support for the airborne assault atRio Hato Airfield, supported by an MH-60 which operated as a Forward Arming and Refueling Point (FARP). Two nine-man teams from the 160th participated in the airborne assaults of Torrijos-Tocumen Airfield and Rio Hato Airfield, and were dropped from Air Force C-141s to set up FARPs, 12-foot (3.7 m) platforms with HE-rocket and minigun ammunition, parts and replacements for the miniguns, and fuel and refueling pumps, hoses, etc. But the FARP dropped at Rio Hato landed out of reach in a marsh, forcing the team to "wet wing" refuel from the MH-60.
The Rio Hato mission originally included nine other MH-60s and four MH-6s. Several hours prior to H-hour, these aircraft and crews were instead sent to support a raid nearColón, Panama, a key PDF stronghold where PDF leaders were believed to be. At H-hour, the helicopters conducted an air assault on a beach house along the coast of Colon. It was during this mission that the first 160th soldiers to die in combat perished when their AH-6 was shot down.
Another force of eight MH-60s and four MH-6s waited on the airstrip with crew aboard, to conduct follow-on raids should the need arise.
After these initial missions, elements of the 160th provided support to special operations forces securing outlying areas, recovering weapons caches, and "hunt for Elvis" – the phrase the men of the 160th used to refer to the search for GeneralManuel Noriega. Four MH-60s, two MH-6s, two AH-6s, and two MH-47s were moved to Ft. Sherman in the north for operations in and around Colon.
The 160th conducted numerous air assault missions over the next two weeks, and on 3 January 1990, the majority of the force went back to Fort Campbell, Kentucky.
The crashed aircraft was recovered and reassembled. It is now on static display at theAmerican Helicopter Museum & Education Center in West Chester, Pennsylvania.
MH-6 Little Birds were part of the initial assault near the Olympic Hotel in theBakara Market ofMogadishu, Somalia. The MH-6s conducted rooftop insertions ofDelta Force soldiers.
After the shootdown of theMH-60L, call sign "Super Six-One", by arocket-propelled grenade (RPG), an MH-6 Little Bird, call sign "Star Four-One", landed in the street next to the downed MH-60 and attempted to evacuate the casualties. The pilot went to assist survivors, successfully pulling two soldiers into the Little Bird, while the copilot laid down suppressive fire from the cockpit with his individual weapon. Under intense ground fire, the MH-6 departed with its crew and survivors.[7]
During the night, AH-6J gunships provided fire support to Rangers and Delta Force operators who were in defensive positions around the crash site of "Super Six-One" and under constant fire from WarlordMohammad Farrah Aidid's militia members.
During the invasion of Iraq in 2003 and up until the end of the war in late 2011, Little Bird pilots took part in numerous missions.[vague] Two AH-6 and two MH-6 helicopters were part of a special operations raid at Al Qadisiyah in western Iraq. AH-6 and MH-6 gave support for the 75th Ranger Regiment during its seizure of the Haditha Dam complex in April 2003.[citation needed]
AH-6 helicopters were also tasked with supporting the rescue mission of Private First ClassJessica Lynch in April 2003.[citation needed]
MH-6 helicopters were part of TF-145, as well as the rescue of three Italian contractors and Polish businessman taken hostage by Iraqi insurgents in 2004.[citation needed]
In September 2009, two AH-6 and two MH-6 helicopters were used in an operation inSomalia byUnited States Navy SEALs to kill wanted terroristSaleh Ali Saleh Nabhan.[8]
