First use of the LAE of Kaiser Marquardt of Van Nuys, CA USA; it is aimed to boost the satellite in GEO from GTO. It consumes monomethyl hydrazine and nitrogen tetroxide. Because it uses advanced materials, the new, high-performance engine operates about 700 degrees Fahrenheit hotter than conventional satellite engines, resulting in greater propellant efficiency and higher performance. It provides a specific impulse of approximately 322 seconds as compared to the 315 seconds provided by standard apogee motors.

XIPS propulsion.

Mission details:

Galaxy 10R, is a replacement for Galaxy 10, lost on the first Delta 3 launch failure. It carries Ku and C band transponders and will be parked at 127 deg W.
The Ariane 4, flight V126, had two strap-on liquid boosters. The three stage vehicle flew from the ELA 2 pad on the coast of French Guiana directly to a 217 x 33232 km x 7.0 deg geostationary transfer orbit.
