Sonar 2076 is a submarine sonar detection system designed by Thales for the Royal Navy. The system comprises an integrated suite of active and passive sonar systems including bow, fin, flank and towed arrays. [1] Known components include: Type 2077 Parian obstacle avoidance sonar; Type 2081 environmental monitor; Type 2094 oceanographic sonar
The S2087 is a Low Frequency Active Sonar (LFAS) and consists of both active and passive sonar arrays. Thales describes the system as "a towed-array that enables Type 23 frigates to hunt the latest submarines at considerable distances and locate them beyond the range at which they [submarines] can launch an attack".

The Royal Navy operated the LR5 Submarine Rescue System, designed for retrieving sailors from stranded submarines. Capable of rescuing up to 16 sailors at a time, the system was deployed to the wreck site of the sunken Kursk .
The CAPTAS-4 is a towed array sonar developed by Thales Underwater Systems to equip first-rank surface combatants.Manufactured in Brest, France, it represents the high-end and most powerful system of the company's CAPTAS (Combined Active and Passive Towed Array Sonar) line of products [1] and equips several first-rank warships of the French Navy as well as those of various export customers.
The Spearfish torpedo (formally Naval Staff Target 7525) is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting ...
These submarines can also be fitted with a dry deck shelter, which allows special forces (e.g. SBS) to deploy whilst the submarine is submerged. [33] More than 39,000 acoustic tiles mask the vessel's sonar signature, part of acoustic qualities that give the Astute class over any other submarine previously operated by the Royal Navy. [34]
Submarine detection systems are an aspect of antisubmarine warfare. They are of particular importance in nuclear deterrence , as they directly undermine one of the three arms of the nuclear triad by making counter-force attacks on submarines possible.
The tribulations in the Tigerfish's development, from its conception in the mid-1950s to the introduction of the unsuccessful Mod 0 variant into Royal Navy service in 1980, prompted the decision to purchase cruise missiles to attack ships from Royal Navy submarines. Versions were: Mark 24-Mod-0 for ASW use. Dive depth 1,150 ft (351 m).
