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 SBL-IFX project.
