Canadian Diesel Submarine Simulated Sinking US Nuclear Carrier in 1981 Exercise
A widely repeated story from the 1981 NATO exercise Ocean Venture '81 claims that a Canadian Oberon-class diesel-electric submarine, costing $80 million, successfully simulated sinking the US Navy nuclear aircraft carrier USS Dwight D. Eisenhower, valued at $5.5 billion. The Washington Post reported in 1982 that the exercise's chief analyst, Lt. Cmdr. Dean L. Knuth, rejected the Navy's favorable interpretation and stated that both Eisenhower and USS Forrestal were successfully attacked. The Navy classified his proposed article about the results. The article examines the controversy, the submarine's stealth capabilities on battery power, and the broader debate over carrier survivability. While the exact details remain classified and disputed, the incident highlights the vulnerability of high-value assets to quiet conventional submarines.
