Type 45 Daring-class Audio Brief (Patreon)

The Royal Navy's Type 45 destroyer, also known as the Daring-class, represents a class of six air defense destroyers that serve as a central component of the UK's naval capabilities. These ships are primarily tasked with air defense, protecting naval forces, and critical locations against enemy aircraft and missile threats.

Design and Construction:

The Type 45 destroyer boasts an advanced design emphasizing stealth, with a sleek structure that minimizes radar cross-section. The ship is approximately 152 meters in length, with a beam of 21.2 meters and a displacement of about 8,500 tonnes when fully loaded. Its construction incorporates extensive use of radar absorbent materials and careful shaping of the hull and superstructure to reduce detectability.

Propulsion:

The propulsion system of the Type 45 is an Integrated Electric Propulsion (IEP) system, combining two Rolls-Royce WR-21 gas turbines with two Wärtsilä 12V200 diesel generators, driving two electric motors. This configuration offers operational flexibility, fuel efficiency, and allows for a top speed in excess of 30 knots. The IEP system also provides substantial power reserves for future weapon and sensor systems.

Armament and Sensors:

The primary weapon system of the Type 45 destroyer is the Sea Viper (PAAMS) air defense system, centered around the Aster 15 and Aster 30 missiles capable of engaging aircraft and missile threats at ranges up to 120 kilometers. For close-in defense, it is equipped with a Phalanx CIWS, a 4.5-inch Mk 8 naval gun, and can also carry up to two Lynx Wildcat or Merlin helicopters for anti-submarine warfare and surveillance roles.

The Type 45's sensor suite is led by the SAMPSON multi-function radar, capable of tracking hundreds of targets simultaneously and providing comprehensive air and surface surveillance. The S1850M long-range radar supports early detection and tracking of threats.

Electronic Warfare and Countermeasures:

The destroyers are equipped with sophisticated electronic warfare systems, including the UAT Mod 2.1 electronic support measures, decoys, and the ability to launch chaff and flares to confuse enemy sensors and missiles.

Operational Use:

The Type 45 destroyers are versatile platforms designed to perform a variety of missions, from area air defense to anti-piracy operations and humanitarian assistance. Their advanced capabilities allow them to operate independently or as part of a carrier strike group, providing integral air defense coverage for the Queen Elizabeth-class aircraft carriers and the fleet.

The Type 45 destroyers are a testament to modern naval engineering and a crucial element of the Royal Navy's surface fleet, ensuring the UK maintains a capable and responsive naval force.
