ex-PC-718


SC-718 served the Navies of the United States and Norway.

SC-497 Class Submarine Chaser:

  • Laid down 22 September 1942 as PC-718 by Fisher Boat Works, Detroit, MI
  • Launched 31 March 1943
  • Reclassified SC-718 in April 1943
  • Commissioned USS SC-718, 25 May 1943
  • Transferred to Norway 12 October 1945 and named HNoMS Hitra
  • Transfered to the State Department, Foreign Liquidation Commission in June 1948
  • Decommissioned in 1958.
  • SC-718 still exists in Norway as a Norwegian Royal Navy vessel, the "Hitra." During the war the U.S. loaned three American-built subchasers to occupied Norway under the lend-lease program and late in the war transferred
    ownership of the three vessels to Norway permanently. Throughout the war they were used in an operation called the "Shetlands Bus", a ferrying service between Norway and the Shetlands Isles which, at high risk, transported
    secret agents and communications equipment into Norway to enable them to keep track of German navy movements all along the Norwegian coast. On return trips the subchasers would take key Norwegian personnel back to
    the Shetlands and to freedom. After the war the three subchasers eventually disappeared. But in 1981 the 718 named Hitra was accidentally discovered half sunk in a Swedish ship's graveyard. A movement began to restore
    her and this was eventually done. Today the Hitra operates as a full fledged subchaser fitted out and equipped exactly as she was during the war, and used for exhibit, education, reunions, etc. Her ship's bell still carries the faint
    engraving of "SC 718" as a reminder of her American roots. She is based in Bergen, Norway.

    Specifications:

  • Displacement 95 t.
  • Length 110' 10"
  • Beam 17'
  • Draft 6' 6" (fl)
  • Speed 21 kts.
  • Complement 28
  • Armament: One 40mm gun mount, one or two twin mount .50 cal. machine guns, two or three depth charge projectiles "K Guns", 14 depth charges with six single release chocks and two sets Mk 20 Mousetrap rails with four
    7.2 projectiles
  • Propulsion: Two 1,540bhp General Motors (Electro-Motive Div.) 16-184A diesel engines, two shafts. (In 2000, having trouble getting replacement parts for these engines, they were replaced with a pair of V-8 Mercedes 550 h.p.
    diesels with Twin Disc gear boxes. Said to run very smoothy with little noise. The pitch of the props had to be adjusted to bring the ship up to 15 kts. speed. The original General Motors 16-184's have been placed into
    protective storage).
