inverted-Y empennage. The airframe is a modified monocoque structure made of aluminum alloy and reinforced fiberglass construction. There is a vertical rack in the target nose section for mounting equipment. Equipment is mounted on both sides of the rack for convenient equipment removal, installation, and checkout. The target is powered by a YJ400-WR-403 variable speed, turbojet engine, which produces a minimum of 190 pounds (240 pounds of thrust E model) of static thrust at sea level. The 16.2-gallon fuel tank is mounted in the fuselage center section. The BQM-74C/E target drone is air launched from either  the  A-6E  or  TA-4J  aircraft.  The  target  can  be surface launched from the ground or a ship. The target flight path is remote controlled by radio commands. A gravity-erected, two-axis, vertical displacement gyroscope  maintains  target  stabilization.  The  target  is equipped with a parachute recovery subsystem and an active  flotation  subsystem.  After  water  entry,  these subsystems keep the target afloat for a minimum of 24 hours.  The  target  has  retrieval  attachments  that  are compatible   with   shipboard   or   helicopter   retrieval equipment. When   the   basic   BQM-74C/E   target   drone   is configured  for  mobile  sea  range  (MSR)  and  on-range target   (ORT)   operations,   specific   mission-peculiar equipment  is  added.  The  mission-peculiar  equipment and  installation  and  checkout  procedures  are  listed  in Maintenance Manual Instructions, NAVAIR 01-BQM-74C-2-1. For further information concerning the basic BQM-74C/E target drone, you should refer to Maintenance Instructions Target Drone Navy Model BQM-74C/E, NAVAIR 01-BQM-74C-2-2. BQM-34A/S TARGET SYSTEM The  BQM-34A/S  target  system  (fig.  8-10)  is  a recoverable, jet-powered target with a service ceiling of 50,000 feet and a maximum speed of 600 knots. Unlike the  AQM-37C,  this  target  requires  extensive  support equipment and preparation before launching. BQM-34E/T MISSILE TARGET The   BQM-34E/T   missile   target   is   a   remotely controlled,  supersonic,  recoverable  target  capable  of speeds up to Mach 1.7 and altitudes of up to near 60,000 feet.  It  is  propelled  by  a  Y-69  turbojet  engine  and  is capable of performing preset maneuvers up to 5 G. Mk 28 Mod 3 This  target  flare  is  used  to  provide  an  infrared source on the BQM-74C/E target during missile firings. Mk 37 Mod 0 This  target  flare  is  used  to  provide  an  infrared source on the missile target to enhance survivability of the target during missile firings. REVIEW NUMBER 3 Q1.
