The Mk-48 is the standard heavyweight torpedo used by the US military, and is mounted primarily on submarines. Surface ships use the smaller Mk46 or Mk50. The Mk-54, in contrast, stemmed from the need for a smaller, lighter, and cost effective advanced torpedo – one that could be dropped from helicopters, planes, and smaller ships. In recent years, the US has moved to modernize and maintain its Mk-48 inventory; the Mk-54 also requires servicing and spares.
Many of these contracts were issued under a total enterprise partnership between Raytheon and the US Navy called Team Torpedo, dedicated to meeting the needs of U.S. and allied naval fleets. Team Torpedo combines Raytheon’s manufacturing, design engineering, and support services expertise with the systems engineering and testing capabilities of Naval Undersea Warfare Center (NUWC) operations in Newport, RI, and Keyport, WA. Now, a new provider has entered the picture. DID has the complete set of contracts below… plus more details regarding the torpedoes involved, and the answer to the question “what the heck is CBASS standard”?
Heavyweight & Flyweight: Mk-48 ADCAP and Mk-54
Heavy Hitter: The Mk-48
The Mk-48 is a huge 533mm torpedo (19 feet long, 3,500+ pounds) with advanced homing, wire guidance capabilities, and devastating consequences when its 300kg warhead hits a target. It is designed to kill both fast, deep-diving nuclear submarines and high performance surface ships, and is carried by US Navy and Royal Australian Navy submarines. The Mk 48 ADCAP has improved target acquisition range, reduced vulnerability to enemy countermeasures, reduced shipboard constraints such as warm-up and reactivation time, and enhanced effectiveness against surface ships. These torpedoes can operate with or without wire guidance, and can use active and/or passive homing, conducting multiple re-attacks if they miss the target. Cost estimates for this weapon are around $2 million each, rising to almost $3 million in some cases with upgrades factored in.
The Common Broadband Advanced Sonar System (CBASS) kit is for the Mk48, and includes a Broadband Sonar Analog Receiver, preamplifier and interfacing hardware. This gives the retrofitted torpedoes the ability to transmit and receive over a wide frequency band, and takes advantage of broadband signal processing techniques to improve their targeting & tracking capabilities. This is especially helpful in shallower waters, where the bottom and other clutter is more likely to be in the way. CBASS kits procured before the end of FY 2007 were for Mk-48 ADCAP Mod 5 and below, and so they included the Torpedo Propulsion Upgrade (TPU) modification required for forebody/ afterbody compatibility. After that, the kits are used with Mk-48 ADCAP Mod 6 torpedoes, which don’t require the TPU.
Initial CBASS contractor Raytheon also manufactures the AN/BYG-1 combat management system used in new American submarines, and scheduled for retrofit to older Los Angeles class boats and the Royal Australian Navy’s Collins class submarines. This reportedly allows for a degree of synergy that improves the Mk-48 ADCAP torpedo’s effectiveness. In 2011, however, Lockheed Martin stepped into the picture with a key contract win for CBASS kits.
The USA, Australia, Brazil, Canada, and the Netherlands are Mk-48 customers, and Turkey has requested them for its new U214 subs. The Mk-48 doesn’t lack for international competitors, though: Britain (Spearfish), France (F21), Germany (Sea Hake), Italy (Black Shark), and now South Korea (White Shark) all produce plausible alternatives for western submarines. Russia, India, Japan, and China also produce their own heavy torpedoes, but they wouldn’t compete with the Mk-48 because the submarines that carry them are local or Russian designs.
Torpedo to go: The Mk-54
The Mk-54 stemmed from the need for a smaller, lighter, but cost effective advanced torpedo that could be dropped from helicopters, planes, and smaller ships. To achieve this, it combined the expensive Mk-50’s search and homing system with the propulsion system of the Mk-46 torpedo (the previous NATO/US standard), and added off-the-shelf electronic components. Its size improves its ability to go after targets in shallower littoral regions, but the torpedo is designed to work in both deep water and near-shore or shallow environments. Cost estimates for this weapon are around $1 million each.
In 2013, the Navy ordered the MK-54 MOD 0 array and transmitters. The MK-54’s sonar array and transmitters hadn’t been produced since the Navy completed MK-50 production in the mid-1990s, as the MK-54’s common parts were just taken from older MK-50 stocks. The new MOD 0s are substantially the same design, but obsolete parts and material have been switched for modern electronics. A new receiver is also part of Northrop Grumman’s contract, and the technology refresh and proof of design testing were accomplished by Advanced Research Laboratory, Pennsylvania State University (ARL PSU).
The MK 54 MOD 1 LWT kit is an upgrade that adds a new sonar array assembly, and improved processing capability. The full kit includes a 112-element array, transmitter, receiver, Processor Group Assembly (PGA), Modular Recording and Exercise Control System Second generation (MRECS2), and associated cables. It’s still a developmental product, under a SBIR Phase III framework. Progeny Systems Corporation, of Manassas, VA owns the intellectual property rights, so they’ve been the sole-source for all contracts.
Look up! The new 737-derived P-8 Poseidon aircraft is spurring the special development of special GPS-guided, high-altitude launch kits for the MK-54. The HAASW add-on kit from Boeing is derived from their JDAM bombs, allowing accurate torpedo drops from 35,000 feet in P-8A Poseidon Increment 2 aircraft, instead of the usual ceiling of several hundred feet. Lockheed and Raytheon have developed similar solutions.
Competitors: The MU90 Eurotorp is the Mk-54’s primary international competitor, and it has been very successful in the international marketplace. It ran into severe problems in Australia, however, and those have taken a long time to sort out. BAE Systems’ Stingray has made a few sales as well, and South Korea’s K745 Blue Shark could become an interesting future competitor. Meanwhile, there are still a lot of Mk-46s in service around the world.

August 14/18: Upgrade kits The Navy is ordering torpedo replacement kits from Lockheed Martin Sippican. The firm-fixed-price, cost and cost-plus-fixed-fee modification has a value of $59.1 million and provides for the production of G&C sections and CBASS kits used on the Mk48 Mod 7 torpedo. The Mk-48 is a huge 533mm torpedo (19 feet long, 3,500+ pounds) with advanced homing, wire guidance capabilities, and devastating consequences when its 300kg warhead hits a target. The Mk48 Mod 7 CBASS is an upgraded version of the MK 48 Advanced Capability (ADCAP) Mod 6 Advanced Common Torpedo (ACOT). CBASS includes a Broadband Sonar Analog Receiver, preamplifier and interfacing hardware. This gives the retrofitted torpedoes the ability to transmit and receive over a wide frequency band, and takes advantage of broadband signal processing techniques to improve their targeting & tracking capabilities. According to the Lockheed’s website the company delivers at least 20 Mod 7 CBASS kits per month to the US Navy. This contract combines purchases for the US Navy and international allies. The governments of the Netherlands, Canada and Turkey will each receive the kits under the US foreign military sales program. Work will be performed at Lockheed’s facilities in Marion, Massachusetts; Braintree, Massachusetts and Lemont Furnace, Pennsylvania. The kits are scheduled for delivery by March 2021.
August 3/18: Dutch purchase The Netherlands may soon receive more torpedoes for its Navy as part of a US foreign military sale. The US State Department is determined to approve the sale of 106 Mk 54 conversion kits for an estimated cost of $169 million. The Royal Netherlands Navy intends to upgrade its current Mk 46 torpedoes to the Mk 54 with the purchase of these kits. The Mk 54 stemmed from the need for a smaller, lighter, but cost-effective advanced torpedo that could be dropped from helicopters, planes, and smaller ships. To achieve this, it combined the expensive Mk-50’s search and homing system with the propulsion system of the Mk 46 torpedo and added off-the-shelf electronic components. Its size improves its ability to go after targets in shallower littoral regions, but the torpedo is designed to work in both deep water and near-shore or shallow environments. The deal would also include torpedo containers, Recoverable Exercise Torpedoes, air launch accessories for rotary wing aircraft and spare parts. The principal contractor will be Raytheon.
June 22/18: Maintencance needed The Navy is contracting Northrop Grumman Systems Corp. for maintenance work on its arsenal of Mk48 heavyweight torpedoes. The $17,9 million cost-plus-incentive-fee, cost-plus-fixed-fee and cost-only contract provides the commanders of the US Atlantic and Pacific fleet’s submarine force with approximately 56,160 man-hours per year to operate the progressive depot-level repair facility and provide depot-level repairable management functions for Mk 48 readiness. The Mk-48 is a huge 19 feet long, 3,500 lb. heavy torpedo with advanced homing, wire guidance capabilities, and devastating consequences when its 600 lb. warhead hits a target. It is designed to kill both fast, deep-diving nuclear submarines and high-performance surface ships, and is carried by US Navy and Royal Australian Navy submarines. These torpedoes can operate with or without wire guidance, and can use active and/or passive homing, and can conduct multiple re-attacks if they miss the target. Cost estimates for this weapon are around $2 million each, rising to almost $3 million in some cases with upgrades factored in. This Work will be performed in Yorktown, Virginia, and is expected to be completed by September, 2018.

July 25/13: MK-54 MOD 0. Northrop Grumman Corp. in Annapolis, MD wins a $46 million firm-fixed price, cost-plus-fixed fee, cost-type contract to produce 428 MK-54 MOD 0 nose array kits. They’ll make proof of manufacturing/first articles, functional item replacement components, and additional spares and production support material, while providing engineering services hours, hardware repair support, test equipment, and warranty options.
All $46 million is committed immediately, and immediate customers include the U.S. Navy (52%, implicitly 223), and exports to the governments of Australia (41%, implicitly 175) and India (7%, implicitly 30). Options could bring the contract’s value to $294.4 million, and bring total production to 3,000 for the USA and Mk-54 export customers.
When asked, the Navy explained that the MK-54’s sonar array and transmitters haven’t been produced so far, just re-used as Government-Furnished Equipment from Navy stocks of 550 Northrop Grumman MK-50s and spares. Mk-50 production ended in the mid-1990s, so those have run out. The “new” MK-54 MOD 0 array and transmitter are substantially the same design, but obsolete parts and material have been replaced with modern electronics. A new receiver is also part of the Northrop Grumman contract, which leverages some of the things NGC learned as lead designer for the current MK48 ADCAP Mod 7 CBASS heavy torpedo upgrade. The technology refresh and proof of design testing were accomplished by Advanced Research Laboratory, Pennsylvania State University (ARL PSU).
Work will be performed in Lititz, PA (40.5%); Annapolis, MD (30.9%); and Santa Barbara, CA (28.6%), and is expected to be complete by July 2016. This contract was competitively procured, with proposals solicited via the E-commerce and FBO.gov websites, and 2 offers received by US Naval Sea Systems Command in Washington, DC (N00024-13-C-6412). See also NGC Aug 14/13 release.

Sept 19/11: 100 MK54. Raytheon IDS in Portsmouth, RI receives a $42.6 million fixed-price incentive, firm-fixed price, cost-plus-fixed fee, cost-type contract for 100 MK 54, MOD 0 lightweight torpedoes. The contract includes options that could push its value to $558.4 million over 4 years, as it buys new weapons, test equipment, spares, engineering, and repair services related to upgrades of US Navy lightweight torpedoes.
Work will be performed in Portsmouth, RI (80%), and Keyport, WA (20%), and is expected to completed by October 2015. This contract was competitively procured via Navy Electronic Business Opportunities website, with 4 offers received (N00024-11-C-6410). See also Raytheon release.
USA: Mk-54s
Aug 11/11: ASROC. The US Department of the Navy issues FBO.gov presolicitation #N0010411RK105:
“The U.S. Navy intends to place an order for repair and upgrade various components for the ASROC MK54 Missile. The Government does not have drawings or required technical data to repair or upgrade thses [sic] components”
ASROC is a missile, which attaches to a lightweight torpedo (RUM-139B with Mk46 or RUM-139C with Mk54) and allows rapid engagement using a warship’s vertical launch cells. Once it reaches the target area, the torpedo drops into the water without the booster, and tracks normally. While Raytheon is the MK54’s manufacturer, VL-ASROC is a Lockheed Martin product; given the lack of government data, one or both of these contractors must be retained.
June 24/11: The US DSCA announces [PDF] India’s request to buy 32 MK-54 All-Up-Round Lightweight Torpedoes, 3 recoverable exercise torpedoes, 1 training shape, plus containers, spare and repair parts, support and test equipment, publications and technical documentation, personnel training and training equipment, transportation, and other forms of U.S. Government and contractor support. The estimated cost is $86 million, but actual costs will depend on a negotiated contract.
India intends to use the torpedoes on its forthcoming 8 P-8i Neptune maritime patrol aircraft, and the numbers involved mark this as an initial familiarity and training buy. Prime contractors are listed as “Boeing Company in St. Louis, Missouri, and a yet to be identified U.S. torpedo contractor.” Which is odd. Technically, Boeing is the P-8i lead integrator, but the Mk-54 is a Raytheon design. On the other hand, Lockheed Martin offers the GPS-guided, high altitude launch HAAWC/Longshot, consisting of an adapter kit mounted on a Mk-54. If India wants HAAWCs, Lockheed Martin could be listed as the contractor.
There is a possible industrial offset agreement in connection with the proposed sale, and implementation will require an unfinalized number of U.S. Government and contractor representatives in-country visits on a temporary basis for technical reviews, support, and oversight.
DSCA request: India MK-54s (32)
May 16/11: Taiwan. Taiwan’s military reportedly plans to budget $860 million to purchase new Mk54 and Mk48 torpedoes over the a 10-year period.
$300 million will reportedly be used to buy 600 Mk54 lightweight torpedoes, replacing existing Mk46s. They’re designed to launch for ships, and from aircraft like Taiwan’s incoming P-3C Orion sea control planes.
Another $160 million will be spent on the purchase of 40 Mk48s, replacing the existing German-made SUT heavyweight torpedoes Taiwan acquired with its 2 Hai Lung II (Zvaardis) Class subs built by the Netherlands. Another $400 million would cover 100 Mk48s, if Taiwan finds a way to source and purchase the 4-8 diesel-electric submarines it wants. Focus Taiwan.
March 31/11: Support. Raytheon Full Service Partnering Corp. in Keyport, WA receives a $47 million cost-plus-fixed-fee, indefinite-delivery/ indefinite-quantity contract for engineering services in support of lightweight and heavyweight torpedo systems.
This effort includes combined purchases for the US Navy (82%), and the governments of Canada (8%), Japan (4%), Brazil (4%), and Turkey (2%) under the Foreign Military Sales Program. Work will be performed in Newport, R.I., and is expected to be complete by March 2016; $50,000 will expire at the end of the current fiscal year. The contract was competitively procured, with one offer received via the Navy Electronic Commerce Online website by the US Naval Undersea Warfare Center Division in Newport, RI (N66604-11-D-0633).
March 23/11: The US DSCA announces [PDF] Canada’s request for 36 MK-48 Mod 7 Advanced Technology (AT) Torpedo Conversion Kits for their existing MK-48 Mod 4 stocks, plus containers, spare and repair parts, weapon system support & integration, publications and technical documentation, personnel training and training equipment, and other forms of U.S. Government and contractor support.
The estimated cost is $125 million, but the actual price will be finalized once a contract is signed. That may not happy very soon, as a federal election has just been forced by the minority Conservative Party government’s fall over its proposed budget. $3.5 million per torpedo does seem rather high for conversion kits, but it is in line with the Netherlands’ July 29/10 request for the same thing.
Canada intends to use the MK 48 7ATs on their Victoria Class diesel-electric fast attack submarines. No technical issues are expected, as the country already has some torpedoes of this type in stock, has significant experience with the MK 48 Mod 4/4M and MK 46 5A(S)W, and has good infrastructure for maintaining these weapons.
DSCA request: Canada MK-48 MOD7 kits (36)
March 4/11: New CBASS supplier.

This contract includes options which could bring its cumulative value to $235.2 million.
Work will be performed in Marion, MA (99%), and Akron, OH (1%), and is expected to be complete by May 2014. This contract was competitively procured via Navy Electronic Commerce Online website, with 5 offers received by US Naval Sea Systems Command in Washington, DC (N00024-11-C-6404).
USA – new CBASS supplier
Oct 5/10: The US DSCA announces [PDF] Australia’s official request to buy up to 200 MK 54 All-Up-Round Torpedoes, 179 MK 54 Flight in Air Material Kits to mount them onto aircraft, 10 MK 54 Exercise Sections, 10 MK 54 Exercise Fuel Tanks, 10 MK 54 Dummy Torpedoes, 6 MK 54 Ground Handling Torpedoes for safe training, plus support and test equipment to upgrade Intermediate Maintenance Activity to full MK 54 capability, spare and repair parts, technical data and publications, personnel training and training equipment, and other forms of U.S. government and contractor support.
It’s an interesting request, because Australia had picked the Eurotorp MU90 as its lightweight torpedo, but an MH-60R pick would require either a MK-54 purchase or expensive integration work. The estimated cost is up to $169 million, and the prime contractor will be Raytheon Company Integrated Defense Systems in Keyport, WA.

July 29/10: The US DSCA announces [PDF] The Netherlands’ official request to buy 40 MK-48 Mod 7 Advanced Technology (AT) Torpedo Conversion Kits, 40 containers, plus support and test equipment, spare and repair parts, weapon system support and integration, publications and technical documentation, personnel training and training equipment, and other U.S. Government and contractor support. The Netherlands wants to upgrade its current stock of MK 48 Mod 4 torpedoes to the MK 48 Mod 7AT, for use on its Walrus Class diesel-electric fast attack submarines. Asked about the difference between this upgrade and the USA’s MK 48 ADCAP, a Raytheon representative relied that:
“The Advanced Technology (AT) configuration was developed to provide compatibility to the launching interfaces of international submarine configurations.”
The estimated cost is up to $150 million, and the prime contractor will be Raytheon Company Integrated Defense Systems in Keyport, WA. The Netherlands won’t require the assignment of any additional U.S. Government or contractor representatives to The Netherlands, though Contractor Engineering and Technical Services (CETS) may be required on an interim basis for installations.
