Introduction

The Fridtjof Nansen class is a Norwegian class of frigates built in Spain. They are modern multipurpose frigates with a balanced set of armament and high quality sensors and systems. All five ships are named after Norwegian explorers.

Layout

The design of the Fridtjof Nansen class is based on the Spanish Alvaro de Bazan class. It is a conventional modern frigate with a reduced radar signature design. The main gun and VLS are mounted at the front. The forward superstructure houses the bridge and SPY-1 radar system. The engines and funnel are mounted in the middle and the hanger and helicopter deck are at the rear.

Firepower

Against surface targets the 8 NSM missiles or single 76mm OTO Melara Super Rapid main gun can be used. Protection against aircraft is provided by a Mk 41 VLS with 32 Evolved Sea Sparrow missiles. A 40mm anti-aircaft gun / CIWS can be installed, but is not fitted. Submarines can be engaged by two twin Stingray lightweight torpedo launchers. Four M2HB heavy machine guns are installed for self-defence. A single NH-90 NFH helicopter is carried for utility and anti-submarine warfare duties.

Electronics

The EAGIS combat data system is the main system on the Fridtjof Nansen class and is connected to a SPY-1F radar and various other sensors. A Link 11 system is fitted for information exchange. The sonar system is a combined active/passive array consisting of MRS 2000 and Mk 2 CAPTAS.

Mobility

The main machinery is a CODAG system consisting of a single LM 2500 gas turbine and two Bravo diesel engines. This results in a maximum speed of 26 knots and a 4.500 nm range at 16 knots. A retractable bow thruster adds maneuvrability.

Users

The Fridtjof Nansen class is only used by Norway, which took delivery of 5 vessels. They replaced the older Oslo class and make up the entire Norwegian frigate force.

Variants
