Operational history
Sri Lanka
The Dvora class has become the work horse of the Sri Lanka Navy, which has deployed it to counter LTTE operations at sea with 12 Dvoras acquired between 1982 and 1988.[1] Since then Dvoras have been made in Sri Lanka and has been the basis for the more advanced Colombo class fast patrol boat built by the Colombo Dockyard Limited.
Taiwan
The Republic of China Navy uses Dvoras as Fast Attack Missile Craft, purchasing two and using them as a pattern for the almost-identical, locally-built Hai Ou-class missile boats (Hai Ou class has three propeller shafts whereas Dvora class has two), 50 built. Both classes, being an anti-ship asset, are armed with additional two Hsiung Feng I anti-ship missiles and have been in ROCN service for over 20 years.
Operators
- Israeli Sea Corps - 9 (Initially 10 were in service, 1 decommissioned after collision with a rocky shoal)
- Sri Lanka Navy - 4 (2 acquired in 1984 and 4 in 1986; 3 sunk in 1993, 1995 and 1996).[2]
- Republic of China Navy - 2 original Dvora acquired in the 1980s and 48 local variant version Hai Ou-class (Seagull), retired beginning in 1999 to 2012 (replaced by 30 Kuang Hua VI-class missile boats).
- Four units (ex-ROCN FABG-7, FABG-11, FABG-29 and FABG-32) received from Republic of China in 2009 as patrol gunboats. All 4 were originally slated for Republic of Malawi in 2008.
- Two units (ex-ROCN FABG-1 and FABG-2) received from Republic of China in 1994 as patrol gunboats.
