Lucky Legs and her big fish, 75 Years ago

North American B-25 Mitchell #43-3981 “Lucky Legs” of the 47th Bombardment Squadron, 41st Bombardment Group, 7th Air Force, prepares to take off from Ryuku Retto, Okinawa for a mission against Sasebo Harbor on Kyushu in the Japanese Home Islands, 28 July 1945. Lucky is carrying a Mark 13/44 GT-1 (glide torpedo), a weapon the particular plane used for the first time, in this mission.

While primarily a Navy-dropped weapon, the Mark 13 was used by the Army in a few instances, such as the 41st BG’s B-25s, and by B-26 Marauder units at Midway and in the Aleutian Islands, the Southwest Pacific, North Africa, and the Mediterranean, with limited success.

With that being said, the Mark 13 was probably the most common air-dropped anti-ship torpedo in history, with more than 17,000 made, and had the distinction of being the U.S. Navy’s final such weapon used in combat, by Skyraiders from USS Princeton against the Hwachon Dam in Korea. Notably, late-war PT-boats also used the weapon as it was lighter than their older Mark 8s. Some 13-feet long and 22.4-inches in diameter (wider than a tube-launched torp) the Mark 13 weighed about 2,200-pounds, including 600 of Torpex high explosives. Once dropped, it could make 33.5 knots to 6,300 yards.

From “U.S. Naval Weapons” by Norman Friedman via Navweaps:

“A review of war experience showed a total of 1,287 attacks [this count only includes those launched by carrier-borne aircraft, other US Navy aircraft launched another 150 torpedoes – TD], of which 40 percent (514) resulted in hits, including 50 percent hits on battleships and carriers (322 attacks, including Midway), 31 percent on destroyers (179 attacks), and 41 percent (out of 445 attacks) on merchant ships.”

More info on the Mark 13, below:

For the record, the 47th BS inactivated 27 January 1946 at Manila and has remained that way while the parent 41st BG endured into the Cold War as an F-4 unit, the 41st TG, until it was inactivated in 1970 at Incirlik. Ironically, the F-4, a tactical fighter, could carry more ordinance than the B-25 of WWII fame.

About laststandonzombieisland

Let me introduce myself. I am a bit of a conflict junkie. I am fascinated by war and warfare, assassination, personal protection and weaponry ranging from spud guns and flame throwers to thermonuclear bombs and Soviet-trained Ebola monkeys. In short, if it’s violent or a tool to create violence it is kind of my thing. I have written a few thousand articles on the dry encyclopedia side for such websites as Guns.com, University of Guns, Outdoor Hub, Tac-44, History Times, Big Game Hunter, Glock Forum, Firearms Talk.com, and Combat Forums; as well as for print publications like England Expects, and Strike First Strike Fast. Several magazines such as Sea Classics, Military Historian and Collector, Mississippi Sportsman and Warship International have carried my pieces. Additionally I am on staff as a naval consultant and writer for Eye Spy Intelligence Magazine. Currently I am working on several book projects including an alternative history novel about the US-German War of 1916, and a biography of Southern gadfly and soldier of fortune Bennett Doty. My first novel, about the coming zombie apocalypse was released in 2012 by Necro Publications and can be found at Amazon.com as was the prequel, Chimera-44. I am currently working on book two of that series: "Pirates of the Zombie Coast." In my day job I am a contractor for the U.S. federal government in what could best be described as the ‘Force Protection’ field. In this I am an NRA-certified firearms, and less-than-lethal combat instructor.
