Zenith Star

Zenith Star was a Directed-energy weapon that started development as part of the US Strategic Defense Initiative.

It included the Alpha laser, a high energy hydrogen fluoride chemical laser, and the LAMP mirror which was a 7 segment adaptive optics mirror.

Zenith Star was never put in orbit, but the Alpha LAMP Integration (ALI) project carried out some ground-based tests.

Legacy
Around 1998 Space-Based lasers were reconsidered and led to the Space Based Laser - Integrated Flight eXperiment (SBL-IFX) project 2000-2002.
