Terrier Improved Orion
Part of Hawk Family
Two stage vehicle consisting of 1 x Terrier + 1 x Improved Orion

AKA: Terrier Orion Improved. Status: Active. First Launch: 1994-04-05. Last Launch: 2016-07-16. Number: 75 . Gross mass: 1,315 kg (2,899 lb). Height: 12.80 m (41.90 ft). Diameter: 0.46 m (1.50 ft). Apogee: 300 km (180 mi).

The Terrier-Orion rocket system was a two stage spin stabilized rocket system which utilized a Terrier MK 12 Mod 1 for the first stage and an Improved Orion motor for the second stage. The vehicle was typically configured with spin motors and the total weight of this configuration, excluding the payload, was approximately 1305 kg.

The Orion motor utilized a clamp-released/load-bearing tail can to interface with the Terrier motor. This was a rail-launched configuration that can be supported at most fixed and mobile launch ranges.

Payload configurations supported by this vehicle included 36 cm and bulbous 44 cm diameters. Payload weights ranging from 90 to 360 kg could achieve altitudes of approximately 200 to 80 kilometers respectively.

Available support systems include the standard 36 cm Ignition Recovery Module Assembly (IRMA), ACS systems, and nose cones of various configurations. The complete cadre of 44 cm diameter support systems was available for use with the bulbous payloads. These included fixed and deployable nose cones; fine, course, rate control, and magnetic ACS systems; separation and despin systems; and forward and aft recovery systems.
