 The Mark XV entered service in 1942 with the Fleet Air Arm, RAF Coastal Command and Royal Navy. It was the first 18-inch torpedo to use Torpex (short for torpedo explosive) instead of TNT. Torpex is 50% more powerful than TNT by mass.
-The Mark XV was the standard airborne torpedo during the last years of the war, and an approximated 591 torpedoes was expended in September 1944. The Mark XV was heavily based on the earlier [[18 inch Mark XII (450 mm)]] torpedo, and therefore had some resemblances with it. The Mark XV used the same burner cycle engine as the Mark XII, but with a higher air vessel pressure. This gave the Mark XV a greater range at 40 knots, compared to the Mark XII at the same speed setting. Further improvement was also made to the constructional strength of the torpedo, allowing for water entry at up to 270 knots. Land-based torpedo aircraft and motor torpedo boats had a heavy warhead load of 247 kg of Torpex, which dramastically increased the impact power of the torpedo. However, for wartime carrier-based torpedo aircraft this warhead load proved too heavy, so they were initally carrying a warhead of 176 kg TNT. Later in the war this was increased to 196 kg of Torpex.

Later in the war this was increased to 196 kg of Torpex.
 While the torpedo carried by aircraft had one speed-setting of 40 knots, the torpedoes used by the navy had a second speed setting at 33 knots. This enabled the torpedoes to have a greater range.
-To increase the probability of a succesfull drop from aircraft, the Mark XV improved the anti-roll gear from the Mark XII by replacing the drum-control gear (DCG) wire drum with a Monoplane Air Tail Mark IV (MAT). The MAT mk4 had ailerons which were gyro-controlled. The gyro equipment was actually stored within the MAT, meaning that for aircraft that had limited space for a torpedo, could use the Mark XV torpedo with the earlier MATs and the DCG.

-The Mark XV torpedo was succeeded by the Mark XVII torpedo, which was further strengthened and modified to sustain a drop at 350 knots. This was possible due to the MAT mk5, which was a MAT mk4 with a parachute to slow down the torpedo. The Mark XVII torpedo could either have a warhead of 272 kg or 196 kg Torpex.

 <!--''Tell us about the tactical and technical characteristics of the torpedo.''-->
 The Mark XV is a mid-war torpedo. It was deigned for both aerial use and use on torpedo boats. Being an aerial torpedo it is smaller than the 21 inch (53.3 mm) torpedoes designed exclusively for use on ships.
 The naval version of the torpedo has an optional "Torpedo Mode" modification which increases the range from 3.2 km to 5 km, but reduces the speed by 7 kph, bringing it to 54 kph.
