The naval MK 41 Vertical Launching System (VLS) hides missiles below decks in vertical slots, with key electronics and venting systems built in. A deck and hatch assembly at the top of the module protects the missile canisters from the elements, and from other hazards during storage. Once the firing sequence begins, the hatches open to permit missile launches of various types. It is also being adapted for land use, as part of the USA’s plan to forward-deploy ballistic missile defense in allied countries.

The Mk.41 is the most widely-used naval VLS in the world, in service with the US Navy and with many countries outside the United States. Lockheed Martin is the system’s prime contractor, with components and canisters provided by BAE Systems Land & Armaments. In September 2011, however, the US Navy assumed the final integrator role.

A Naval Swiss Army Knife: The MK 41 VLS

More than 11,000 MK.41 VLS missile cells have been delivered, or are on order, for use on 186 ships and 19 ship classes, in 11 navies around the world. This system currently serves with the US Navy as well as the Australian, Canadian, Dutch, German, Japanese, New Zealand, Norwegian, South Korean, Spanish, and Turkish navies. The UK seems to be next.

The MK 41 VLS can hold a wide variety of missiles: anti-air and ballistic missile defense (Sea Sparrow, ESSM, Standard family), anti-submarine (VLASROC), land-attack (Tomahawk) and more. One simply drops different missile canisters into the MK 41’s common interface.

The Housing: VLS Cells

The MK 41 VLS is itself available in 3 different sizes, to meet differing hull and mission requirements:

• The Strike length MK 41 is the largest system accommodating the widest variety of missiles, up to and including Tomahawk cruise missiles for land attack, and SM-3s for ballistic missile defense. Its capabilities cover almost every mission in naval warfare: anti-air, anti-submarine, ship self-defense, land attack, and ballistic missile defense. In future, it also has the potential to carry anti-ship missiles, like the LRASM/OASuW. A land-based version will make up part of the USA’s “Aegis Ashore” missile defense complexes in Romania and Poland.
• The Tactical length Mk 41 is over 7 feet shorter than the Strike length, and can accommodate a variety of missiles up to approximately 18.5 feet in length. SM-2 Standard and RIM-162 Evolved SeaSparrow air defense missiles, and VL-ASROC anti-submarine missiles, will fit in a tactical length cell.
• The Self-Defense Launcher (SDL) is specifically designed to carry self-defense missiles for small ships, and is shorter and lighter than the other variants. Its size and weight are designed to accommodate smaller ships like corvettes and frigates, as well as aircraft carriers with limited deck and hull space.

The MK 41’s most recent Baseline VII upgrade was rolled out in 2004, upgrading the module’s electronics. Advances include cell-based architecture, commercial off-the-shelf (COTS) processors, a modern real-time operating system, programming written in the object-oriented C++ language, Ethernet communications, and fiber optic channels, all within an open architecture approach. These changes opened the door to compliance with the US Navy’s Open Architecture Initiative, added RIM-162 Evolved Sea Sparrow Missile capability, and improved life cycle maintenance and future upgradability.

This Baseline VII configuration is currently fielded on new U.S. Navy destroyers (DDG 91 and later); efforts are underway to modernize the USA’s CG-47 Ticonderoga Class missile cruisers, and eventually older Arleigh Burke Class destroyers as well.

The Blades: Canisters & Inserts

The key to the system’s flexibility is its canisters, which come in different vertical sizes. The canisters serve as missile shipping and storage containers. During missile launch, they provide an internal launch rail and help contain the rocket motor’s exhaust gas. Tactical-length canisters can use adapters in order to fit into strike-length Mk.41 cells, but you can’t fit a strike-length canister into a smaller tactical-length cell. Designations include:

• Mk.13: Tactical length canister for standard size SM-2 air defense missile variants
  
• Mk.14: Strike length canister for BGM-109 TLAM Tomahawk cruise missiles
  
• Mk.15: Tactical length canister for VL-ASROC anti-submarine rockets
  
• Mk.21: Strike length canister for SM-2 Block IV and SM-3 Block I long-range air/ballistic missile defense missiles. The MOD 3 variant supports the new SM-6 successor to the SM-2.
  
• Mk.25: Tactical length Quad-pack canister for RIM-162 Evolved SeaSparrow air defense missiles
  
• Mk.29: Strike length canister for the future SM-3 Block II ballistic missile defense missiles, which are wider. Uses more composites for lighter weight.

Inserts can also enhance a cell’s flexibility. Lockheed Martin’s Extensible Launching System (ExLS) is, in effect, a semi-permanent Mk.41 canister that acts as a quad-pack adapter, allowing ships to fire smaller weapons like Nulka anti-missile decoys, RIM-116 RAM block 2 defensive missiles, or even small land attack missiles, from their Mk.41/Mk.57 vertical launchers. ExLS can also be hosted in a ship on its own, creating an independent launch system that competes with the Mk.41 SDL.

The MK41 VLS system’s leading competitor is DCNS’ Sylver family of launchers. They equip the French Navy’s Charles de Gaulle nuclear aircraft carrier, the Franco-Italian Horizon Class frigates, the UK’s Type 45 destroyers, and Saudi Arabia’s LaFayette-derived Sawari II frigates, among others. In 2005 the Sylver launcher was also picked to equip the multi-role Franco-Italian FREMM frigates, which have been ordered by France, Italy, Algeria, and Morocco.

Valued at an estimated $70 million, the sale includes four vertical launching systems, spares, handling equipment, test equipment, operator manuals and technical documentation, US Government and contractor engineering, training, technical, and logistical support services, and other related elements of logistical support. Lockheed Martin will act as lead contractor. The systems will be integrated on Finland’s upcoming fleet of four new corvettes, and follows a series of FMS clearances earlier this month for naval weapons as part of an ambitious naval modernization program.

July 8/16: Chile’s Navy is to receive MK 41 Vertical Launching Systems (VLS) armed with the Evolved Sea Sparrow Missiles (ESSMs). The systems and missiles will be installed as part of upgrades on three UK-built Type 23 frigates at a cost of $140 million. Raytheon, BAE Systems and Lockheed Martin are the contractors implementing the upgrade. At present, the former Royal Navy frigates operate the legacy GWS-26 Sea Wolf anti-air missiles so the ESSM’s represent a significant upgrade in capabilities.

March 21/16: Lockheed Martin is to restart production on its MK 41 Vertical Launching System with a ribbon-cutting ceremony planned its Middle River plant in Baltimore County, Maryland on March 24. According to an invitation to media, the MK 41 VLS is “the only launching system capable [sic] launching anti-air, anti-submarine, surface-to-surface and strike missiles and can receive orders from multiple weapon control systems to handle every warfighting mission.” The news comes as Lockheed was awarded a potential three-year $197.6 million contract modification to carry out computer program baseline development work on the US Navy’s Aegis combat systems, of which the MK 41 is a core component.

Dec 12/14: N00024-13-R-5332 Award. Lockheed Martin Mission Systems and Training is awarded a $235.3 million firm-fixed-price contract for MK 41 electronic and mechanical modules and related equipment, that can reach $356.8M with options.

They’ll support of research, development, test, evaluation, upgrades, operation, maintenance and product improvements for the US Navy (96.02%), and for the governments of South Korea (3.49%); the Netherlands (0.38%) and Canada (0.11%).

All funds are committed immediately. Work will be performed in Minneapolis, MN (87%); Brea, CA (12%); and Aberdeen, SD (1%), and is expected to be complete by September 2013. $89,928 will expire at the end of the current fiscal year, on Sept 30/13 (N00024-13-C-5325).

June 28/13: Multi-Year Canister deal. BAE Systems’ US Combat Systems group in Minneapolis, MN, is being awarded a $40.3 million firm-fixed-price contract, covering FY 2013 orders for MK 14 MOD 2 (Tomahawk), MK 21 MOD 2 (SM-3), MK 21 MOD 3 (SM-6), and MK 25 MOD 0 (ESSM) VLS Canisters; ancillary hardware; and associated support equipment. All funds are committed immediately. This is the initial award for the advertised FY 2013 – 2017 contract (q.v. May-June 2012 entry), though its period of performance could run through 2019 if all options are exercised. BAE cites a maximum possible value of over $400 million.

The initial $40.3 million contract combines purchases for the U.S. Navy (96.7%) and the government of Thailand (3.3%) under the Foreign Military Sales (FMS) program. In January 2013, Thailand opted for a limited initial buy of 9 RIM-162 ESSM missiles. They’ll equip its 2 Chinese-built Naresuan Class frigates, which carry American Mk.41 VLS systems.

Work will be performed in Aberdeen, SD (90%), and Minneapolis, MN (10%), and is expected to be complete by by July 2015. This contract was competitively procured via FBO.gov and the Navy Electronic Commerce Online websites, but just 1 offer was received. The Naval Sea Systems Command, Washington, D.C. manages the contract (N00024-13-C-5314). See also BAE Systems.

June 27/13: Support. As the Mk.41’s Mechanical Design Agent, BAE Systems announces a $91.4 million contract from the U.S. Navy to develop technical solutions for new canister (incl. Mk.29) and missile integration, as well as launcher improvements, and continued support of the Aegis Ballistic Missile Defense Program and Aegis Ashore. BAE.

May 15/13: MBDA MoU. MBDA signs an MoU with Lockheed Martin Lockheed Martin that has the potential to shake up the naval missile industry. It sounds innocuous: both companies agree to jointly explore the market for the integration of MBDA naval missile systems into Lockheed Martin’s MK-41 Vertical Launch System, and ExLS VLS/cell insert.

They’ll begin with a late 2013 demonstration involving Britain’s new CAMM-M Sea Ceptor missile, but the implications reach far beyond. MBDA has a wide array of naval missiles for both air defense and precision attack, but most are compatible only with DCNS’ rival SYLVER system. Adding those missiles to the Mk-41 would give it overwhelming dominance in the global naval market. Read “CAMM Opener for the Naval Missile Market: MBDA & LMCO’s MoU” for full coverage.

MK.41 MoU with MBDA

Feb 13/13: New plan for FY13-17. NAVSEA cancels the presolicitation that it had issued in the summer 2012 (N00024-12-R-5320) and replaces it with N00024-13-R-5332. In it they announce their intent to issue a single solicitation in March 2013 for the MK 41 VLS Launcher Production Contract for FY13-17 launchers, ancillary hardware, and associated support equipment in support of US Navy, AEGIS Ashore, and Allied Navy requirements.

These requirements consist of up to 120 modules (10 USN DDG 51 Class shipsets), 3 AEGIS Ashore modules, up to 48 Allied Navy modules, and VLS upgrade kits and spares for Aegis Modernization (AMOD) and DDG modernization programs.

Mechanical and electronic requirements may end up addressed by a single contract or separate ones.

Sept 14/12: FY 2012 Canisters. BAE Systems Land and Armaments’ US Combat Systems Division in Minneapolis, MN receives a $7.3 million contract modification for MK 21 MOD 2 SM-3 canisters, as well as canisters to fit SM-2, SM-6, and RIM-162 Evolved Sea Sparrow air defense missiles, VL-ASROC anti-submarine weapons, and RGM-109 tactical Tomahawk long-range cruise missiles.

Work will be performed in Aberdeen, SD (87%) and Minneapolis, MN (13%), and is expected to run until July 2014. US Naval Sea Systems Command, Washington Navy Yard, Washington, D.C., is the contracting activity (N00024-10-C-5349).

July-Aug 2012: pre-RFP. On July 2 NAVSEA issued a presolicitation (N0002412R5320) in advance of issuing an RFP in September for the production of MK 41 launchers and ancillaries over the FY13-17 period to align with the MYP procurement of the underlying ships. They intend to award a single Firm Fixed Price contract via full and open competition. The award is planned for January 2014, with work lasting until 2020. Like in the case of the separate RFP for canisters, allied countries are taken care of within this contract.

Since then NAVSEA has updated its presolicitation, including a short set of questions and answers posted on Aug 20/12 following an Industry Day on Aug 7/12. Offerors must be US-based, but the winning prime can subcontract to qualified foreign subcontractors. NAVSEA has indicated, however, that do not want any subcontractor to have more than 20% of the total contract. The slides used during that event are classified Distribution F – thus, you will not find them posted here, nor on FBO.gov or NECO.

May-June 2012: Canisters. NAVSEA released a presolicitation (N0002412R5314) in preparation of an FY13-17 production contract for MK 41 VLS MK 14 Mod 2, MK 21 Mod 2, MK 21 Mod 3, and MK 25 Mod 0 canisters. An Industry Day took place on June 4. The final RFP is expected for the summer 2012, while the award planned for May 2013 will reward the winning bid with a Firm Fixed Price contract via full and open competition. As of February 2012, Chris Deegan, the Executive Director PEO IWS, estimated [PDF] the value of this award at $710M.

June 20/11: Mk41 for British Type 45 destroyers? Raytheon Missile Systems VP Ed Miyashiro is telling journalists that a number of other platforms are being looked at for NATO/European ballistic missile defense, including Britain’s Type 45s. The ship class’ MBDA Aster-30 missiles have just begun land tests against ballistic missiles, but Raytheon’s SM-3 family has both a longer testing record, and an SM-3 Block II that promises very significant performance improvements. For cash-strapped European governments, it also comes with much cheaper missile defense development costs, thanks to American and Japanese advance work.

The issue would be integration. Spanish F100 frigates are the most straightforward, with the same AN/SPY-1D radars and Mk.41 Vertical Launch System (VLS) as American ships. The same AEGIS BMD upgrade set used in American destroyers would suffice. Dutch and German F124 frigates, and the pending Danish Ivar Huitfeldt Class ships, also carry the MK.41 VLS, but use higher-performance Thales APAR and SMART-L radars. That requires additional integration and modification work, but all 3 classes are using a shared core system. The British, French, and Italian ships would be the most work. While they all share a similar core air defense system, they all use different radars, while sharing key electronics and DCNS’ Sylver VLS. That means both electronics work, and physical changes to the weapons array. In his conversations, Miyashiro mentions that they’re looking into the possibility of fielding SM-3 compatible inserts in DCNS’ Sylver A70 VLS, which is the required size for the 6.6 meter SM-3. Britain’s Type 45 Daring Class has space for adding the larger Sylver A70 launchers up front, but Miyashiro has reportedly said that they’re also looking at the possibility of inserting the Mk.41 VLS there.

A Mk.41 VLS would require some combat system integration, in exchange for very wide flexibility beyond the SM-3s. It would also give the Daring Class the ability to use an array of new weapons, including Tomahawk land attack cruise missiles, which current British doctrine will only fire from submarines.

Sept 30/10: Successful thermal model testing of the new Mk.29 VLS canister on board the US Navy’s Self Defense Test Ship. NSWC Port Hueneme engineers took the lead in coordinating the event requirements and schedule, prepared the ship for testing, reviewed test planning documentation, provided 7 other VLS canisters for the test event and conducted the onload and offload of the 8 VLS canisters to and from the test ship.

The canister and missile used were the MK 29 Mod 0 Prototype P1 canister and SM-3 Blk IIA engineering unit inert missile. The Mk29 canister is designed to house the future SM-3 Block IIA , which is 21″ wide throughout. The SM-3 Block 1s, which fit into Mk21 canisters, are just 13.5″ wide above the booster stage. The MK 29 canister design is also a departure from previous VLS canister designs, using mostly composite materials in order to reduce weight. US NAVSEA.

Aug 11/10: Lockheed Martin announces a successful test-firing of a Nulka decoy from their new Extensible Launching System (ExLS) insert.
