On December 27, 2007, one UFAC Series II was destroyed and another damaged during an encounter between Sri Lankan Navy and Sea Tiger patrol boats between Delft Island and Mannar.

[4] The boats of the Series I are 24 m (78 ft 9 in) long with a monohull with a vibration-free deck, powered by twin MTU main engines developing 1,630 kW (2,190 hp) each, driving Kamewa water jets.

[5] Their thrust-vectoring propulsion system allows Series III to function in shallow waters at draughts of 1.2 m (3 ft 11 in) facilitating special operations forces delivery on enemy shores and catastrophe relief missions.

[1] The two coastal surveillance vessels built for the Maldivian Coast Guard are very similar to the Series III Ultra Fast Attack Craft.

[6] Currently all Colombo-class boats have been designed to allow for the installation of Typhoon 25-30 mm stabilized cannon which can be slaved to state-of the art mast-mounted, day and night all weather long range electro-optic systems.
