The boats of the Astute class are powered by a Rolls-Royce PWR2 (Core H) (a pressurised water reactor) and fitted with a pump-jet propulsor. The PWR2 reactor was developed for the Vanguard-class ballistic missile submarines and has a 25-year lifespan without the need for refuelling.
9 sty 2023 · The Royal Navy’s Astute class submarines: Part 1 – development and delivery. In the first of a series of articles focussing on the Astute class SSNs, we look at the programme’s history and how decisions made decades ago continue to impact today’s fleet.
23 kwi 2019 · The Astute class submarines were designed from the outset to be fitted with a Dry Deck Shelter (DDS) which significantly enhances their ability to covertly deliver special forces. Using unclassified public domain sources, here we examine the history, design and operation of the DDS in RN service.
Also onboard the Astute Class of submarines is the lethal Spearfish torpedo. Weighing nearly two tonnes, this heavyweight torpedo can attack targets up to 14 miles away (which can increase to 30 miles at low speed) and is capable of blowing an enemy submarine clean out of the water.
The Astute-class submarines are the first nuclear submarines to be fully designed using a three-dimensional, computer-aided environment. The submarines are 97m long and weigh 7,400t. They have a maximum operational endurance of 90 days and can reach speeds of up to 29 knots.
Astute Project. The UK Ministry of Defence (MoD) issued the Invitation to Tender (ITT) for the Astute Class Submarine in July 1994 and the contract was awarded in March 1997. This contract was for 3 submarines together with support for the initial 8 years of service life.
