Project history

Bazan design was confirmed 29.2.2000 after competition with Lockheed Martin. Contract was signed 23.6.2000. Program became the single largest Norwegian defence project ever undertaken. Some of armament and sensors may have been transferred from Oslo class. Able to operate with no personnel in the engine rooms. Signature-reduction measures include topside shaping, acoustically hooded machinery and IR suppression system, wet-down spray system, propeller shaft grounding and a flexible drive train. GRP radar mast. Combat system is a variant of USN Aegis. Space and weight are reserved for second Mk 41 VLS for Standard SM-2 missiles, 1 40mm gun or CIWS and SLQ-25 Nixie torpedo decoy. Ships have problems with corrosion.

Naval service

Helge Instad collided 8.11.2018 with 250m-long Maltese tanker Sola TS on coastal fairway N of Bergen, was abandoned(!) by crew and, бstaying on the move, with efficient engines, but unmanned ran aground and partially sunk in shallow water 13.11.2018. She was salvaged in March 2019 and sold for scrap. Estimated cost of ship's repair would exceed the cost of her building three times.
