4.9 AERIAL ROCKET CONTROL SYSTEM (ARCS),
2.75 INCH.
CAUTION
2.75 inch Hydra–70 Rocket configura-
tions (Fuse/Warhead/Motor), are limited
to the following flight conditions:
Firing of M439/M261/Mark 66 and
M442/M257/Mark 66 at ranges less than
1000 meters and/or airspeeds greater
than 90 knots is not authorized.
The ARCS (fig 4-6) is a light antipersonnel assault weap-
on. The ARCS consists of a rocket control panel located in
the pilots station and four station directors located in each
of the four wing station pylons. The ARCS permits the pilot
to select the desired type of 2.75 inch folding fin aerial
rocket (FFAR) warhead, fuze, quantity, and range. The
lightweight nineteen-tube launchers can be mounted on
any of the four wing stations. There are three modes of fir-
ing rockets: pilot, CPG, and cooperative (precision) mode.
The FCC limits the fire control solution to a maximum
range of 6000 meters (MK-40) and 7500 meters (MK-66).
