 The aircraft became the T.3 Velos, a twin-float seaplane.The Velos differed from the standard Dart T.2 in having a two-seat cockpit with a rear-mounted .303 in (7.7 mm) Lewis Gun, an increased weapons load with four 230 lb (104 kg) bombs mounted under the wings and provisions to fly as either a seaplane with floats or with a conventional undercarriage.In 1925, a small batch of four aircraft was built at Brough Aerodrome for the Greek Navy.
