Warplane Wednesday: Savoia-Marchetti SM79 Sparrowhawk

At 0025 hours, an Italian Savoia-Marchetti SM79 Sparrowhawk penetrated Force H’s defence screen unchallenged. Once the bomber loosed its payload, Indomitable realised she was under attack and began to turn into the torpedo. The turn came too late, however, and the missile slammed into the port side of the carrier, opening a 28-square-foot hole in the hull.

– Excerpt from Eagles over Husky

By mid-1943 the Savoia-Marchetti SM79 Sparviero (Sparrowhawk) was obsolete, but it was retained as a torpedo bomber out of necessity. The Regia Aeronautica’s torpedo bomber force was mostly ineffective during Operation Husky. There weren’t enough aircraft or crews left to achieve enough concentrated strength to mount successful raids against Allied shipping. The torpedoing of HMS Indomitable on the night of 15/16 July 1943 was an impressive exception.
