On March 19, the guided-missile submarine Florida fired more than 90 of the roughly 120 Tomahawk cruise missiles that took down Libyan air defenses, clearing the way for NATO strike planes. It was the major-combat debut for America’s fleet of “SSGN” subs. Each of the four vessels packs up to 154 Tomahawks, making them some of the world’s most powerful warships.
But there’s a problem. The SSGNs, commissioned in the last five years, are actually modified ballistic-missile submarines dating from the 1980s. Around 2026, their nuclear power cores will wear out. At that point, the Navy must replace the subs … or lose a huge portion of its missile firepower. But building new submarines the size of the SSGNs could cost up to $8 billion apiece, nearly half what the Navy spends on ships every year. In other words, way too much.
Fortunately, Electric Boat in Connecticut, the Navy’s main submarine-builder, has a plan. Instead of designing new SSGNs from scratch, Electric Boat intends to pack the current Virginia-class attack submarines with extra missiles — and give them new eyes and ears in the form of sophisticated underwater and flying robots. The meaner, smarter Virginias wouldn’t carry as many missiles as today’s SSGNs, but at just $2 billion a pop, the Navy could afford many more of them.
The Virginia missile-boat plan is key to preserving the Navy’s overwhelming firepower advantage. It’s also the subject of my latest feature for AOL Defense.
