40: 1015: 796: 570:. Its straightforward design made it easier to maintain than most other helicopters, its relatively compact 26 feet (7.9 m) main rotor made it easier to use tight landing zones. While its light aluminum skin could be easily penetrated by small arms fire, it also crumpled and absorbed energy in a crash while the rugged structure protected key systems and its crew. The OH-6 was relatively difficult to shoot down, and its occupants would often survive forced landings that would have likely been fatal onboard other rotorcraft. The remaining H-13s were promptly withdrawn in favour of the OH-6s. Typically missions were flown during the daylight, starting at dawn; common roles included the clearance of landing zones and general intelligence/observation flights. 1545: 435: 1122: 779:
Guard's Army Aviation Support Facility (AASF) at Gulfport, Mississippi, for two weeks of qualification training in the aircraft. The following two-week mission was to Yuma for night operation training. The AH/MH Little Birds were lifted by a single C-5 Galaxy, and two C-130 Hercules, along with all support kits for the battalion. Crews trained side by side with the 160th for all operational concepts. The 1-245 modified infantry night vision goggles and worked to develop the necessary skills for rapid deployment with Little Birds and C-130s.
596:. This teamwork was actively encouraged by Army officials, and led to the development of so-called "hunter-killer" tactics that sought to flush out and eliminate hostile ground targets. Such a team would have normally comprised a single OH-6 that would fly relatively slow and at a low altitude while attempting to spot the presence of enemies. If the OH-6 came under fire, the nearby Cobra would then strike at the revealed enemy. As to indicate the position of concealed enemy ground forces, the observer in the OH-6 would mark the spot using a 291: 1265: 1078: 1300: 1133: 1243: 413:, that he lost over $ 100 million to construct 1,370 airframes. It was reported that Howard Hughes had directed his company to submit a bid at a price beneath the actual production cost of the helicopter in order to secure this order. Accordingly, this tactic had resulted in substantial losses being incurred on the contract with the U.S. Army; the company had allegedly anticipated that an extended production cycle would eventually make the rotorcraft financially viable. 559: 707: 574: 1007: 804: 746: 426:. Following a competitive fly-off, the Army requested the manufacturers to submit sealed bids. Hughes bid $ 56,550 per airframe, while Bell bid $ 54,200. Reportedly, Hughes had consulted at the last moment with Real, who recommended a bid of $ 53,550. Hughes, without informing Real, raised the bid by $ 3,000, and thus lost the contract to Bell. 1,420 of the OH-6A would be produced, not counting the other derivatives. 394: 1221: 1155: 1199: 499:, a word created by pronunciation of the LOH (light observation helicopter) acronym of the program that spawned the aircraft. (Loach is also the name for numerous stream-dwelling carnivorous or insectivorous fishes, especially common in South-East Asia, which specialise in hunting among substrates and dense cover.) During 1964, the U.S. Department of Defense issued a memorandum 1177: 1056: 1034: 788: 600:, assisting other units in effectively firing upon them. Over time, the effectiveness of this pairing was such that enemies would often decide against firing on the relatively vulnerable OH-6 in fear of the response that would be unleashed by the AH-1. Prior to the arrival of the AH-1, "hunter-killer" teams often relied on the firepower from armed models of the 219:. The Model 369 had a distinctive teardrop-shaped fuselage that was crashworthy and provided excellent external visibility. Its four-bladed full-articulated main rotor made it particularly agile, and it was suitable for personnel transport, escort and attack missions, and observation. During May 1965, the U.S. Army awarded a production contract to Hughes. 778:
On 1 October 1986, to help meet the increasing demands for support, the 1-245th Aviation Battalion from the Oklahoma National Guard, which had 25 AH-6 and 23 UH-1 helicopters, was placed under the operational control of the 160th.

During 1967, following price escalations for the OH-6, the U.S. Army reopened the program to bids for as many as 2,700 additional airframes beyond the 1,300 OH-6s already contracted. Following a competitive fly-off and a sealed bidding process, Hughes lost the contract to Bell, resulting in the

Operation Honey Badger 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. But the Army decided that it would be more prudent to keep the unit in order to be

To remedy this shortcoming, the Army began developing a special aviation task force to prepare for the next attempt to rescue the hostages: 726:. The architects of the task force identified the need for a small helicopter to land in the most restrictive locations and that was also easily transported on Air Force transport aircraft. They chose the OH-6A scout helicopter to fill that role, and it became known as the 350:

Due to price escalations for both the OH-6 and spare components, the U.S. Army opted to reopen bids for the program in 1967. Accordingly, during 1968, Hughes submitted a bid to build a further 2,700 airframes.

During June 1972, they were deployed to a secret base in southern 3777: 3441: 655:(PS-44), where one of the helicopters was heavily damaged during a training mission late in the summer. On the night of 5–6 December 1972, the remaining helicopter deployed a wiretap near 671:. Shortly thereafter, the aircraft were returned to the U.S., where they were dismantled and converted back to a standard configuration; they continued to be operated as such for a time. 775:.
