Common Characteristics

Three trainable 18-in tubes on the deck, two on the beams forward and one centreline aft.[1]

Three 3-pdrs, arranged in the same pattern.[2]

In mid-1904, the Royal Navy ordered the replacement of two 5-barrel .45-in Nordenfelt machine guns with .45-in Maxim guns on each of fifty-seven first-class torpedo boats. This figure must have included most or all of this class.[3]

The boats were larger than the preceding T.B. 98 class at 200 tons and delivered the same performance, but also with poor endurance.
