INS Yaffo (אח"י יפו) is an Israeli missile boat of the Shayetet 3 Flotilla, one of ten Sa'ar 4.5-class missile boats. She was launched in 1998 at Israel Shipyards in the Port of Haifa. She has been a part of Israeli Navy since July 1, 1998.[1][2]

Construction

Sa'ar 4.5-class missile boats are enlarged variant of the Sa'ar 4 class.[3] New ships were quite longer, in order to take an augmented armament.[3]

INS Yaffo was built at Israel Shipyards in the Port of Haifa.[1][2] She was launched in 1998 and finished within few months.[1][2]

The quadrant angle is 85°, the weight of the projectile is 6 kg (13 lb), the range is 16 km (9.9 mi) and the rate of fire is 85 rounds per minute (RPM). There are also two single Oerlikon 20 mm cannon with a range of 2 km (1.2 mi) and rate of fire of 900 RPM and one double (or quadruple) station for M2 Browning machine guns.
