quick and effective mine clearance capability to complement existing methods and others under development for the Navy's Airborne Mine Countermeasures (AMCM) Program. In 2018 it was announced that RAMICS was cancelled "because of poor performance in early testing, incompatibility with MH-60s, and programmatic decision to upgrade Airborne Mine Neutralization System (AMNS) to perform near-surface mine neutralization mission" Observation and other light helicopters HH-2C Seasprite Emerson TAT-102K A version of the TAT-102 (Tactical Armament Turret-102) designed specifically for use on the HH-2C helicopter, the TAT-102K mounted a single M134 Minigun in a fully traversable turret (for specifics see the information for the TAT-102A in the AH-1 Cobra entry). A single such turret would mounted in the nose of the aircraft. The weight of the mount was not suitable for such a small helicopter and the turret was often removed. OH-6 Cayuse (and MD 500 Defender) XM7 The XM7 system provided twin M60 machine gun on the Hughes OH-6 Cayuse series of helicopters. It is unclear if both guns were mounted together or whether they were mounted one on each side of the aircraft. As of 1969 the system was listed with the comment "development suspended," likely in favor of the XM27. This system was also tested on the YOH-5A during August 1964. XM8 The XM8 system provides a mount for one M129 40mm grenade launcher for either the OH-6 or OH-58 light observation helicopters. The system is provided with an XM70/E1 sight and 150 rounds of ammunition. The XM8's mount is interchangeable with the M27 system. This system could also be mounted on the OH-58 Kiowa, and was tested on the YOH-5A during August 1964. M27 Series The M27 system provides a mount for one M134 7.62×51mm machine gun (Minigun) for either the OH-6 or OH-58 light observation helicopters. The system is provided with an XM70/E1 sight and a MAU-56/A delinking feeder with 2000 rounds of ammunition. The system has no movement in azimuth, but has 10 degrees of elevation and 24 degrees of depression. The initial XM27 featured a mount similar to a gunpod, which was quickly exchanged for a more aerodynamic fairing, as well as improvements to the ammunition stowage and other equipment on the XM27E1. The XM27E1 was standardized as the M27. The fairing was removed entirely because for ease of maintenance and to reduce weight on the M27E1. The M27's mount is interchangeable with the XM8 system.
