Why no TASM (Tomahawk Anti-Ship Missile) after 1991?
The nuclear (TLAM-N) and anti-ship (TASM) variants of the Tomahawk were withdrawn in the early 1990s as the Cold War came to an end. TASM was withdrawn because there was no longer any chance of blue-water engagements against a navy with large, high-value targets like the Soviets, and many of the missiles have since been converted to land attack. The TLAM-N was withdrawn as per a 1991 agreement with Russia to not deploy nuclear weapons at sea other than strategic ballistic missiles.
