EH-60A/C Quick Fix

The EH-60A/C Special Electronic Mission Aircraft(SEMA) wasbasically a UH-60A outfitted with a 1,800 pound Quick Fix IIB electronics package that allows the aircraft to intercept, monitor, locate and jam enemy radio transmissions. Externally the EH-60A/C Quick Fix differs from the basie UH-60A Black Hawk by the installation offour dipole antennas mounted on the fuselage and a retractable whip antenna mounted under the fuselage. The prototype installation madę its first flight on 24 September 1981 and the following test program was completely successful. Original plans called for the conver-sion of some 130 UH-60As to the EH-60 configuration.

Before the conversion program got into fuli swing, the Army elected to update the aircraft and redesignate them as EH-60C. Due to budget cuts, the original program was cut back and only sixty-six EH-60Cs were completed. The last of these were delivered to the Army in September of 1988.

YEH-60B SOTAS

The YEH-60B was another conversion of a UH-60A Black Hawk to meet the Army's Stand-Off Target Acquisition System (SOTAS) requirement. The prototype first flew in February of 1981 with a large, rotating Motorola radar antenna mounted under the fuselage. The position of the radar antenna reąuired the installation of long extendable telescopic main landing gear legs to provide ground clearance during landing and ground maneuvering. This version of the Black Hawk never went into production sińce development was halted in September of 1981 in favor of the J-STARS program.

The EH-60A Quick Fix contains an electronics package that can intercept, monitor, locate and jam enemy radio broadcast. The Quick Fix Black Hawks are equipped with four dipole antennas on the rear fuselage and a retractable whip antenna under the fuselage. (Sikorsky)
