It only takes one of these subs to wipe out any adversary. We've got 18 of them and they're REALLY hard to find.
Moreover, the "stealth" ability of the submarines was significantly improved over all previous ballistic-missile subs. Ohio was virtually undetectable in her sea trials in 1982, giving the U.S. Navy extremely advanced flexibility.[14]
The Ohio class was designed in the 1970s to carry the concurrently designed Trident submarine-launched ballistic missile. The first eight Ohio-class submarines were armed at first with 24 Trident I C4 SLBMs.[5]
Beginning with the ninth Trident submarine, Tennessee, the remaining boats were equipped with the larger, three-stage Trident II D5 missile.[6] The Trident I missile carries eight multiple independently targetable reentry vehicles, while the Trident II missile carries 12, in total delivering more destructive power than the Trident I missile and with greater accuracy.
Starting with Alaska in 2000, the Navy began converting its remaining ballistic missile submarines armed with C4 missiles to carry D5 missiles. This task was completed in mid-2008. The first eight submarines had their home ports at Bangor, Washington, to replace the submarines carrying Polaris A3 missiles that were then being decommissioned. The remaining 10 submarines originally had their home ports at Kings Bay, Georgia, replacing the Poseidon and Trident Backfit submarines of the Atlantic Fleet.
