DCNS's F21 Heavyweight Torpedo has Entered its Final Development Phase | Navy Recognition - 23 June 2017
Quote
DCNS has just performed a qualification firing of the F21 torpedo as part of the Artémis programme led by the DGA (Direction Générale de l’Armement). The DGA aims to equip all French Navy nuclear submarines with this heavy torpedo, the highest performing one of its generation.

The F21 heavy torpedo was designed to neutralise enemy vessels and submarines. With a range in excess of 50km and a speed greater than 50 knots, the F21 is foreseen for operation not only in deep waters but above all in coastal areas with high levels of noise and dense shipping. Thanks to its a significant computing power that allows for exceptional real-time processing capacities, the F21 torpedo benefits from an advanced mission system and extended autonomy. These technical characteristics considerably widen its possibilities for tactical use with an unequalled target discrimination capacity, including in very challenging environments.

About the F21 torpedo
The F21 torpedo is the only new heavy torpedo development in the world. Its characteristics are significantly superior to all other heavy torpedoes currently in service. Beyond its exceptional performance levels, its on-board tactical intelligence makes this torpedo a precursor for what tomorrow’s underwater drones could be.

In an announcement from 2014, DCNS said a prototype of the weapon had been undergoing tests in the Mediterranean Sea since 2013.

The contract, under which DCNS was to deliver 100 of the torpedoes to the navy, was awarded by the French Defense Procurement Agency (DGA) in 2008.

The wire-guided torpedo is 6 meters long, weighs 1.5 tonnes and has a range of 50 kilometers traveling at speeds between 25 and 50 knots.

F21 is operated through the MIGAL fire control system which serves as the interface between the torpedo and the submarine’s combat information centre.

Indian Black Shark torpedo deal for Navy might be revived | Defense news - June 23, 2017
Quote
Italy's Whitehead Sistemi Subacquei S.p.A., a subsidiary of Leonardo, might be reconsidered to supply Black Shark torpedoes for French Scorpene submarines currently being built in India, according to sources in the Indian Ministry of Defence. 

This follows observations made by India's attorney general on the legality of issuing tenders and its subsidiary defence companies, which are facing probes on charges of alleged corruption.

In June of last year, MoD announced the cancellation of a $200 million deal for Black Shark torpedoes, but MoD sources said the tender was not formally cancelled and that no intimation of the cancellation was conveyed to the Italian company.

The Black Shark torpedoes, if contracted by the Indian government, will be licensed produced in India with transfer of technology in certain critical areas at state-owned Bharat  Dynamics Limited, or BDL, in Hyderabad.   

A total of 98 heavy-weight torpedoes are to be procured out of which the seller would quote for 20 torpedoes in fully formed condition, and the remaining 78 torpedoes will be license produced at BDL.

NGC Awarded MK 48 Heavyweight Torpedo Transducer Array/Nose Assembly Production Contract | Navy Recognition - 06 July 2017

Quote
The U.S. Navy has awarded Northrop Grumman Corporation (NGC) a $9.6 million contract, with options up to $40.5 million, to produce the Transducer Array/Nose Shell Assembly of the MK 48 heavyweight torpedo. The MK 48 is the primary offensive weapon deployed from all U.S. Navy submarines.

The initial contract covers engineering and production of 45 MK 48 torpedo Transducer Array/Nose Shell Assemblies. Three additional options allow for up to 45 units apiece, for a total of up to 180 systems over five years. The contract also includes orders for spare parts and engineering support services. The Transducer Array is the main sensor used to acoustically detect, locate, and guide the torpedo to its intended target.

MADEX 2017: LIG Nex1 Unveils New Tiger Shark Heavy Weight Torpedo | Navy Recognition - 25 October 2017
Quote
Talking to Navy Recognition at MADEX 2017, an LIG Nex1 representative explained that the new Tiger Shark is set to replace the existing White Shark (K731 Baek Sang Eo) heavy weight torpedo in Republic of Korea Navy (ROK Navy) servcice.

We learned at the show that Tiger Shark will be using the same battery type (Li Ion) and technology as the one used on the recent Blue Shark light weight torpedo. Blue Shark is deployed on surface ships, marine helicopters and anti-submarine patrol aircraft as a means to strike enemy submarines. It is capable of penetrating 1.5 meter-thick steel.

According to LIG Nex1, Tiger Shark follows the development of White Shark, Blue Shark and Red Shark. This new version of torpedo is developed to strike enemy surface ships and submarines from a distance and is expected to enhance the viability of submarines.

Video: F21 Artémis Heavyweight Torpedo | Navy Recognition - 13 February 2018
Quote
French company Naval Group opened the doors of its underwater weapon facility in Saint-Tropez so that Navy Recognition may bring you an exclusive video report on the latest technologies in terms of torpedoes, UUVs and anti-torpedo countermeasures. The site located on the French Riviera has been developing and producing underwater weapons and systems since 1912.

The TAPS programme aims to improve the engine efficiency of the US Navy’s MK48 heavyweight torpedo. Phase I will explore increasing the efficiency of the Otto-fueled engine that currently powers the MK48.

If awarded, Phase II of the programme will include integrated full-scale system testing in an MK48 propulsion section.

Israel takes new torpedo into service | Janes - 21 June 2018
Quote
The Israel Defense Forces (IDF) announced on 19 June that is has acquired a new type of torpedo that it calls the Kaved (heavy) for its submarines.

< snipped >

He said the Kaved is made by a non-Israeli defence company that he did not name, but that future upgrades and all maintenance would be conducted in-house by the navy. It will equip Israel’s three older Dolphin submarines as well as the new three new-generation boats, the last of which is expected to be delivered by the German company TKMS in 2019.

The source described the Kaved as a very high-speed weapon that could hit both surface and sub-surface targets, including those at depths of “hundreds of metres”. Unlike the navy’s previous type, the new torpedo has a digital sonar guidance system that “lets us conduct upgrades in the future without changing hardware” and makes the weapon difficult for a target to evade by manoeuvring, the source said.
