SENIOR RUBY

The SENIOR RUBY system is a radar emission monitoring electronic intellitence [ELINT] sensor package carried by the U-2R. As of 1996 the "special" [aka SIGINT] sensors had not been upgraded since 1991 and were in several different configurations. Thus in 1996 the House Intelligence Committee directed a budget increase of $40 million for SENIOR RUBY, SENIOR SPEAR, and SENIOR GLASS commonality upgrades. The Committee directed the Air Force to upgrade the SPEAR/RUBY sensors to the SENIOR GLASS configuration, and upgrade the SENIOR GLASS systems to an open architecture configuration consistent with an architectural approach approved by the Defense Cryptologic Program manager.
