Long Range Intercept Experiment LORAINE

Another proposal was to use technology then under development for a maneuvering re-entry vehicle for ballistic missiles. ROTHR defined a series of resolution cells (each quite large); it could only say whether a bomber was or was not in each cell. Normally a cell would be far too large for a missile's active seeker to search, which was why ROTHR was considered a surveillance tool rather than a fire control sensor. However, a sensor on board a missile approaching the bomber stream from above, ie from space, might view the entire resolution cell. It turned out that a ballistic missile, LORAINE, could be fired from a standard veetical launcher cell, and plans called for equipping its manoevering re-entry vehicle with a millimetre-wave radar. The weapon would dive so fast that the bomber would have little chance of escaping. The space aspect of the system would have been the high-capacity link betwee ROTHR and the firing ship. LORAINE was not ready for tests until 1990, by which time the Cold War, and the Outer Air Battle, were both effectively over.

This is from Seapower and Space, pg 241, by Norman Friedman. Does anyone have more information on this missile? According to the lexicon hosted on FAS.org it was originally known as Ballistic Intercept Missile.

LORAINE was DARPA's program for the kill vehicle's seeker. It was a small, powerful phased array system designed by Raytheon, and supposedly was very advanced for its time.

"Ballistic Intercept Missile. A technology base is being developed within the Ballistic Intercept Missile program to provide a capability for long range fleet and CONUS defense. Key technologies under development are the sensor and navigation system for control of the weapon during the end-game kill. Three combined sensor and navigation concepts were identified in FY 1980-FY 1981. Development of these concepts will be carried through detailed design. A single concept will be selected for fabrication and flight test prior to transfer of the technology base to the Air Force."

Apparently funded out the stategic technology program at DARPA during the early 80s, it (probably) transitioned elsewhere. General Research Corporation of Santa Barbara did several studies of the concept under contract to DoD in the early 80s, a FOIA request may unearth them.
