spearfish torpedo history
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 ship warfare (ASuW) capability. Spearfish patrolled in the Java and Flores seas and made unsuccessful torpedo attacks on two cruiser task forces. The warhead has the lethality against double hull submarines and large displacement surface ships; it is programmed to detonate on impact, or by a proximity fuse when the torpedo passes under the target’s hull.The weapon is currently undergoing an upgrade that improves its homing, warhead and tactical systems. As such, only (5) were ever produced. By David Hambling, technology expert. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface ship warfare (ASuW) capability. Spearfish can also operate autonomously from the time of launch.Its propulsion system is based on a gas turbine with pump producing variable speeds across the entire performance envelope, including a fast sprint in the terminal stage of an attack. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface ship warfare (ASuW) capability. Tactical software has been extensively refined through real-time, hardware in the loop simulations and demonstrated in more than 500 in-water trials and exercise firings.
Designed by BAE Systems Whitehead Division Spearfish is undergoing an upgrading phase expected to complete in 2020.Relying on a complex transducer array of active and passive homing techniques to acquire, identify and prosecute naval targets, using advanced beam forming techniques to optimize performance in different environments. - Defense Update: High power transmissions and sophisticated signal processing enable Spearfish to accurately discriminate targets from background noise and ensure high resistance to acoustic countermeasures and/or evasive maneuvers. This will last until 2019.On 15 December 2014, the Ministry of Defence awarded BAE Systems a £270 million contract to upgrade the Spearfish torpedo. The Fairey Spearfish was a 1940s British torpedo bomber designed and built by Fairey Aviation for the Fleet Air Arm. It weighs two tons and measures five meters in length.
The guidance section located in the mid-body of the torpedo comprises a powerful computer that handles all functions – from propulsion to homing, and attack techniques.Spearfish swims toward its target while linked to the submarine via wire link, that exchanges commands and target data over long distance. The Spearfish torpedo (formally Naval Staff Target 7525) is the heavy torpedo used by the submarines of the Royal Navy. The torpedo is driven by a pump-jet coupled to a Hamilton Sundstrand 21TP04 gas turbine engine using Otto fuel IIand hydroxyl ammonium perchlorate as oxidiser. The fleet will begin receiving the improved torpedoes by 2020 and complete the upgrade in four years and prepare the weapon to challenge future threats. The upgrade includes a new insensitive-munition warhead from The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Spearfish torpedoes are stored and serviced at In 2009, an upgrade programme began, leading to further sophisticated advances in Spearfish's homing, warheads, tactical and fuelling systems, as well as an upgraded guidance link.

In a typical engagement, Spearfish will run out wire-guided to the general vicinity of the target and then conduct a covert passive search. The torpedo is driven by a pump-jet coupled to a Hamilton Sundstrand 21TP04 gas turbine engine using Otto fuel II and hydroxyl ammonium perchlorate as oxidiser. The US Navy's submarine service is easily the most powerful ever fielded in the history of submarine warfare. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. In a typical engagement, Spearfish will run out wire-guided to the general vicinity of the target and then conduct a covert passive search. The Spearfish torpedo is a dual-purpose wire-guided weapon and provides both anti-submarine warfare (ASW) and anti-surface ship warfare (ASuW) capability, replacing the Tigerfish torpedo which was withdrawn in 2004. It was one of the largest single-engine aircraft to ever operate from a British aircraft carrier. A microprocessor enables the torpedo to make autonomous tactical de
At full speed of 80 knots the Spearfish can strike targets at a range of 14 miles, and, at low speed, it increases the range to more than 30 miles.Once at the close range, the torpedo accelerates to sprint speed and uses active sonar to classify and home in on its target. Everything moves slowly underwater because it's a thousand times denser than air and produces far more drag. Spearfish torpedoes used by Navy subs are getting an upgrade from BAE Systems that will make them even better Spearfish torpedo being loaded aboard a Royal Navy submarine By Alan Tovey , … Apart from protecting troops and bases, Iron Dome will be able to protect long-range defense systems such as the THAAD, which could be vulnerable to unconventional threats such as short-range missiles, cruise missiles and drones. But now researchers have found ways of overcoming this drag to create high-speed, and highly lethal, underwater weapons. In a typical engagement, Spearfish will run out of wire in the general vicinity of the target where it will conduct a covert passive search to acquire the target for the final phase. Seen as revolutionary, World War II ended before full production could go into effect. The Spearfish Torpedo is used by the Royal Navy (Image: BAE Systems/MoD). The addition of an oxidiser improves the specific energy of the fuel by reducing the fuel-richness of the Otto fuel. The addition of an oxidiser improves the specific energy of the fuel by reducing the fuel-richness of the Otto fuel. Should Spearfish fail to hit the target on its first attack, it automatically selects an appropriate re-attack mode until it successfully concludes the engagement.
