The 2 inch medium trench mortar, also known as the 2-inch howitzer, and nicknamed the "toffee apple" or "plum pudding" mortar, was a British smooth bore muzzle loading (SBML) medium trench mortar in use in World War I from mid-1915 to mid-1917. The designation "2-inch" refers to the mortar barrel, into which only the 22 in (560 mm) bomb shaft but not the bomb itself was inserted; the spherical bomb itself was actually 9 in (230 mm) in diameter and weighed 42 lb (19 kg), hence this weapon is more comparable to a standard mortar of approximately 5–6 in (130–150 mm) bore.

The Type 99 designation was given to this mortar as it was accepted in the year 2599 of the Japanese calendar (1939).
