MIM-72 Chaparral

It was intended to be used along with the M163 VADS, the Vulcan ADS covering short-range short-time engagements, and the Chaparral for longer range use.

Known as the MIM-46 Mauler, it was based on a modified M113 chassis carrying a large rotating A-frame rack on top with nine missiles and both long-range search and shorter-range tracking radars.

Army strategy from the mid-1950s PENTANA study was based on having embedded mobile anti-aircraft capability, and Mauler's delays put this entire program in question.

MICOM's report was cautiously optimistic, concluding that the Sidewinder could be adapted very quickly, although it would have limited capability.

The main concern was that at shorter distances the missile would not have time to lock onto the target before it flew out of range, so to serve this need a second vehicle based around the M61 Vulcan cannon was specified.

Both would be aimed manually, eliminating the delay needed for a fire control system to develop a "solution".

Four missiles were carried on the launch rails, with eight extras stored below the launcher with their fins and wings removed.

1974 saw the introduction of the MIM-72C, used the advanced AN/DAW-1B seeker with all-aspect capability, as well as a new doppler radar fuze and M250 blast-frag warhead.

MIM-72E retrofitted "C" of the late 1970s using the M121 smokeless motor, which greatly reduced the smoke generated on firing, thus allowing easier follow-up shots and making it harder for enemy aircraft to find the launch site.

The rosette scan seeker of the Stinger POST was adapted to the Chaparral by Ford in a program beginning in 1980.

By this point in time the system was already being removed from regular Army service, and being handed over to the National Guard.
