A great find for any military collectible enthusiast. In 1967 Detachment 1, 428th Tactical Fighter Squadron, began testing pre-production F-111As under the code name Harvest Reaper. Though problems remained, the USAF sent six of these F-111As to Thailand in March 1968 for operational tests called Combat Lancer. Combat Lancer F-111As flew single aircraft precision strikes at night or in poor weather at low altitude. The enemy had little or no warning because the F-111A crews did not have to visually see the target to hit it, and they could strike on the first pass. Highly praised by its crews, the F-111A did not need aerial tankers, fighter cover or surface-to-air missile (SAM) protection like other aircraft. Though the F-111A showed great promise, it had serious problems. Accidents or malfunctions caused the loss of three F-111As and four crew members in 55 combat sorties (one mission by one aircraft equals one sortie). After the third aircraft loss, combat testing ended. For any unsatisfactory reason, item can be returned within 30 days for full refund (less S&H fee).
