The Common Anti-air Modular Missile: Britain’s Versatile Air Defense Missile

May 27, 2014

Britain’s Royal Navy currently uses Seawolf missiles as the primary air defense system for its Type 23 frigates. They’re updated versions of a missile that was used during the 1982 Falklands War, but modern threats demand more. Britain also needs to equip its Type 26/27 Global Combat Ship frigate replacements, and could use an option that raises the number of air defense missiles carried by its Type 45 air defense destroyers.

The answer to all of these problems is being developed as one component of Britain’s GBP 4 billion, 10-year “Team Complex Weapons” partnership with MBDA. It’s a quad-packable, intermediate-range air defense missile with its own active radar guidance, which re-uses a number of features and technologies from British fighter jets’ AIM-132 ASRAAM short-range air-to-air missile. Not only will it serve on British ships, but it’s set to field as an Army air defense missile, and may even fly on future British fighters.

The Common Anti-air Modular Missile (CAMM)
A quick terminology note: FLAADS, the Future Low-Altitude Air Defense System, is the British designation for the program as a whole, which is projected to involve FLAADS (M) at sea, and FLAADS (L) on land. CAMM is the missile, which MBDA uses as a general base reference, but they sometimes mention “CAMM-M” and “CAMM-L” specifically. The naval CAMM-M version and its integration with ship systems is marketed globally under the name “Sea Ceptor”.

CAMM: Performance and Positioning

The CAMM missile’s range remains vague. Reports have cited 500 square nautical mile coverage, which amounts to a 12.6 nmi circle. That’s acceptable for a point defense replacement, but MBDA refers to air defense at ranges “greater than 25 km”, as well as effectiveness against threats riding on the water. That would give it more versatility than the Seawolf missiles it will replace, and a range that compares very favorably with short-range peers like IAI/RAFAEL’s Barak-1, Denel’s Umkhonto, and MBDA’s Crotale NG that sit in the 15 km/ 8 nmi or less range.

MBDA’s response to the saturation threat was to use active homing radar guidance and a 2-way datalink for the missile, removing any strain on limited radar illuminators. It’s similar to Raytheon’s approach with the much longer-range and more sophisticated SM-6, but in a simpler, more limited, and cheaper design. The SM-6 will be able to use the ship’s more powerful radar as an option, and be cued by other vessels over the horizon, but Sea Ceptor can’t do those things. The ship’s radar sees the incoming threat, the CAMM missile is fired, the datalink updates the missile with the current location of the threat, and CAMM’s own seeker takes over once it’s close enough.

A wide variety of ships could make good use of a missile like that, especially a missile that doesn’t need ultra-sophisticated ship radars and illuminators/ trackers in order to be effective. MBDA’s use of a piston-driven “soft launch” approach removes another big obstacle to integration on small ships like corvettes or FAC (Fast Attack Craft), widening the potential market even further. On the software and hardware end, MBDA is reportedly re-using a number of elements from the high-end PAAMS system that equips advanced British, French and Italian anti-aircraft destroyers.

Within the global market, CAMM-M/ Sea Ceptor seems to fit somewhere in between short-range bolt-on naval defense systems like MBDA’s Crotale or Raytheon’s RAM; and medium-range vertical-launch missiles like MBDA’s Aster-15 or Raytheon’s RIM-162 Evolved Sea Sparrow. That’s actually a pretty useful niche. It encompasses the main danger zone for saturation anti-ship missile attacks, which threaten to overwhelm the targeting (illuminator) capabilities of ships that rely on older radar designs and/or semi-active radar homing missiles.

There will always be a temptation for navies to choose medium-range missiles for their superior protection of other ships, and smaller ships in particular create a temptation to default to bolt-on defenses. If budgets don’t allow more expensive missiles, or navies decide that a smaller ship needs to do better than point defenses, Sea Ceptor’s main competitor will be MBDA’s own VL-MICA IIR/ARH missile family.

CAMM Platforms: Sea, Land, and Air

In 2013, Britain confirmed its Type 23 Duke Class frigates, its forthcoming Type 26 frigates, and its Type 45 Daring Class air defense destroyers as the missile’s initial platforms. The Type 23 Duke Class will be the 1st in-service platform, with refits taking place from 2015 – 2021.

MBDA has confirmed to DID that the naval Sea Ceptor will be packed into Type 23 Seawolf vertical launch tubes as a 1 for 1 replacement. Reports also indicate that the missile is designed to be quad-packed into DCNS SYLVER A50/A70 launchers on ships like Britain’s Type 45 destroyers, or in American Mk.41 tactical/strike length cells in common use by navies around the world.

That capability will be an especial help to the Type 45 Daring Class air defense destroyers, whose single-packed SYLVER A50 VLS cells left them with a low number of carried anti-aircraft missiles compared to their global peers. Giving up 12 Aster-15/30 missiles to get 36 Asters and 48 CAMM-Ms is a good trade. Fortunately, heavy FLAADS (M) re-use of elements from the Type 45′s PAAMS combat & launch system should make integration relatively simple.

Compatibility with the globally popular Mk.41 Vertical Launch System under an MBDA/Lockheed Martin MoU opens an even wider market for Sea Ceptor. New Zealand’s ANZAC Class frigates are the first example, with refits beginning in 2016. Britain’s Type 26 frigates haven’t officially settled on their vertical launch system, so they’re also a potential beneficiary.

On land, FLAADS (L) would use the CAMM missile packed onto a truck mounted container, plus a containerized command and control cabin. Because the missile carries its own radar, FLAADS fire units aren’t sold with their own radars, just a secure MBDA-developed datalink. Fielding requires integration of the FLAADS (L) command module with existing air defense systems for cueing. This may seem like a limitation, but it actually makes the system quite dangerous. The fire units don’t have an emitting radar to give their location away and attract enemy attacks, and cueing from a variety of radar and non-radar assets makes it very difficult to silence the missile battery.

A FLAADS (L) prototype was rolled out in the summer of 2009, and is still under development. CAMM-L is cued as the future replacement for Britain’s Rapier missile batteries, but it will be a few years before it’s ready to be exported.

Future years may also see a CAMM-A successor to the AIM-132 ASRAAM, flying on British fighters. ASRAAM is currently guided by imaging infrared, but there are already air-to-air missiles, like the medium-range Russian AA-10 and French MICA, that come in both radar and IR versions. Short-range missiles haven’t used radar guidance over the last couple of decades, but giant strides in fighter radar capabilities, and the CAMM design’s long range for its class, make this a thinkable future option.

Oct 28/13: UK.UK secretary of state for defence Philip Dunne answers a Parliamentary question by saying that Sea Ceptor refits on the Type 23 frigates will be installed as part of their long-term refit program. That program will also outfit the ships with new Artisan 3D radars and other equipment, and refits are scheduled to run from 2015 – 2021. Sources: Portsmouth’s The News, “Frigates to be fitted with new missiles from 2015″.

Oct 7/13: New Zealand.The Royal New Zealand Navy will upgrade its 2 ANZAC Class frigates with MBDA’s CAMM/ Sea Ceptor for air defense, rather than following Australia’s ANZAC upgrade and replacing the ship’s RIM-7 Sea Sparrow missiles with Raytheon’s RIM-162 Evolved Sea Sparrow.

New Zealand is the 1st Sea Ceptor export customer, and they’re also the 1st customer to benefit from MBDA and Lockheed Martin’s MoU (q.v. May 15/13) around the Mark 41 Vertical Launch System.

New Zealand’s air defense upgrade is expected to be cheaper than Australia’s, and is also expected to be cheaper per missile, while providing a different set of performance advantages in the short term. CAMM’s active guidance is currently an advantage compared to the RIM-162 ESSM missiles aboard upgraded Australian ANZACs, in exchange for shorter range. Both missile types can be quad-packed, giving their 8-cell Mk.41 vertical launchers a maximum load of 32 air defense missiles. The trade-off is that Australia’s ESSMs can use the ship’s more powerful radar for guidance, in exchange for additional work tying the missile into the frigate’s combat system. ESSM Block 2 will probably add an active guidance option, erasing CAMM’s edge and retaining longer range, but that isn’t even in the design stage yet. Sources: MBDA, Oct 7/13 release.

RNZN picks Sea Ceptor

Sept 10/13: Testing.CAMM has a successful launch test from a Lockheed Martin ExLS vertical launcher, using MBDA’s piston-driven cold launch approach. This is the first test under the May 2013 MoU between the 2 firms.

ExLS is a quad-pack insert for Mk.41 Vertical Launch System cells, but the release also describes a “3-cell stand-alone ExLS CAMM launcher” that can be used on smaller ships. MBDA’s cold launch technology is a big plus in that market. The missile’s is launched high by piston, then pitched toward horizontal by small mid-body maneuvering thrusters before the main rocket motor ignites. That allows for bolt-on naval solutions, without worrying about about launch flames damaging surrounding equipment. Sources: MBDA, Sept 12/13 release.

Sept 10/13: Production.The UK Ministry of Defence announces the 1st CAMM production contract: GBP 250 million (about $393 million) for the Sea Ceptor/ CAMM-M. Final assembly will take place at MBDA’s Lostock facility, with 9 Tier-1 subcontractors distributed across sites in England and Scotland.

Sea Ceptor is being delivered under the Team Complex Weapons Portfolio Management Agreement, which will create a common missile stockpile for a future planned land system.

The UK’s announcement of the missile’s platforms is equally significant. Sea Ceptor will be retrofitted to Type 23 Duke Class frigates beginning in 2016, serve aboard the forthcoming Type 26 frigate as its primary air defense system – and complement the Aster missiles on the Royal Navy’s Type 45 destroyers. Sources: UK MoD, Sept 10/13 release | MBDA, Sept 9/13 release.

Production contract & Platforms

Sept 10/13: IMU.MBDA is working with United Technologies’ UTC Aerospace to create a MEMS-based Inertial Measurement Unit for use in its missiles guidance, navigation & control system. Current IMU technologies use higher-cost options like fiber optics, and a Micro-Electro-Mechanical Systems unit has the potential to be smaller, weigh less, and cost less. The joint project will be backward-compatible with an existing UTC Aerospace Systems MEMS IMU, which may make upgrades simpler.

A CAMM Missile picture is shown on MBDA’s release, and it would be a logical platform for the new technology. Sources: MBDA, Sept 10/13 release.

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.

The implications reach far beyond CAMM. Britain has already been considering adding a set of Mk-41 cells to the Type 45 destroyer, in order to hold SM-3 ballistic missile defense missiles. Adding CAMM to those cells would make the drop-in even more attractive, by giving the Type 45s two things they don’t currently have: snap-launch anti-submarine defenses (VL-ASROC), and a larger array of air defense missiles (quad-packed CAMM). Beyond Britain, MBDA has a wide array of naval missiles, and adding those missiles to the Mk-41 would give that VLS overwhelming dominance in the global naval market.
