The antiship variant of the Bat (SWOD, for "Special Weapons Ordnance Device", Mark 9 Modification 0) eventually saw combat service beginning in April 1945 off Borneo, dropped by Consolidated PB4Y Privateers (one bomb mounted under each wing) at altitudes of 15,000 to 25,000 feet (4,600 to 7,600 metres) at airspeeds of 140 to 210 kn (260 to 390 km/h).
Several Japanese ships were sunk and the kaibokan Aguni was damaged from a range of 20 nmi (37 km), which is frequently miscredited as being sunk by a destroyer.
Several Bats were also fitted with modified radar systems (SWOD Mark 9 Model 1) and dropped on Japanese-held bridges in Burma – the same targets that the MCLOS-guidance, half-ton (AN-M65 GP bomb) weight VB-1 Azon PGM ordnance was designed to take on – and other land-based targets.
The Bat's pioneering radar guidance system was easily confused by radar land clutter, particularly against targets close to shore.
About a total of 2,600 Bat missiles were deployed.

After the war, the naval designation ASM-N-2 was applied to the unit.

The Privateer was the primary launch platform for the Bat, but other aircraft were also modified to launch the weapon, including the Vought F4U Corsair, Curtiss SB2C Helldiver, and Grumman TBF Avenger.
The primary post-World War II aircraft to carry the weapon was the P-2 Neptune.
