The U.S Navy has received its first Block V configured Tomahawk missile from Raytheon, paving the way to provide the fleet with an upgraded capability.

These first Block V missiles are from the existing Tomahawk Block IV inventory, and have been recertified and modernised for fleet use, according to NAVAIR here.

“This is the next big advancement in Tomahawk capability, and a major achievement for the program,” said Capt. Red, program manager for the Tomahawk Weapons System program (PMA-280).

“We’re focused now on delivering advanced capability to the fleet by recertifying and modernizing our Block IV inventory, and by contracting production Block V missiles.”

Raytheon say it is conducting the mid-life recertification process at its Camden, Arkansas facility.

“The process replaces life-limited components in Block IV missiles to enable their remaining 15 years of service life, and provides the opportunity for the missiles to receive Block V modernizations. All Block IV missiles will undergo recertification and modernization.”

Block V Tomahawk missiles feature a NAV/COMMs upgrade that maintains the capability for In-Flight Target Updates and Improved Navigation.

Future Block V capabilities will add to the NAV/COMMs upgrade and include the Maritime Strike Tomahawk (MST) variant, designated as Block Va; and the Joint Multiple Effects Warhead System (JMEWS), designated as Block Vb.

  1. What’s the chance the Type 26 will get these and what will happen to the torpedo launched versions that the astutes use as i thought the production line had closed for them.

  2. Getting the Maritime Strike Tomahawk (MST) variant would suddenly give us an anti-ship missile with a 1000 miles reach. Beats the Harpoon with its very limited reach for sure. A game changer?

    I read somewhere that to upgrade the IVs costs about $250,000 per missile. Can the ones we use for the subs be upgraded or are they a special sub variant?

    • Possibly this, if we intend to go with the current US manufactured ASM.

      “The successful LRASM Boosted Test Vehicle (BTV) flight on 4 Sep ’13 at WSMR Desert Ship Range, demonstrated an LRASM launch from a MK 41 VLS canister using the proven Mk-114 booster.

      Lockheed Martin is investing in the surface-launch LRASM effort to reduce program risk and accelerate time to fielding an OASuW capability on US Navy surface combatants.

      LRASM can be employed from DDGs and CGs with only software modifications to existing launch control systems. LRASM is the low-risk and low-cost solution for our naval warfighter.”

  3. I managed to find this, so it may very well be on the cards.

    “After the Tomahawks used by the U.S. military are upgraded, it is possible the United Kingdom, the only other nation with Tomahawk cruise missiles would begin modernizing its arsenals, Red said.

    U.S. law covering foreign military sales says systems and weapons must be fielded first in the United States.

    “We’re still working through that” in Washington and London, Red said.”

    • Basically every 10 years we buy about 65
      1995 65 mk3
      2004 64 mk4
      2014 65 mk4

      So they may look to another similar purchase in 2024/5 or they may get an entirely different missile. I doubt upgrading would be considered worthwhile.

      • Thanks for the dates of the buys…. I think it highlights quite clearly that perhaps we need to invest in a much more modern system, particularly for anti ship use…..

        • For a very low cost we can convert an already in use missiles to offer a very long stand off range. Just because the missile is old(ish) doesn’t mean it’s not good (think B52s), and with the enhancements will offer a cheap, long-ranged missile that far exceeds anything the currently in use Harpoon. I think it would be folly not to upgrade at least half of your Tomahawks to the Va variant.

          The US now has four medium to long-range anti-ship missiles (Tomahawk Va, NSM, LRASM and SM6), yet we get stuck in the belief that we need one and only one due to supply chain concerns and so on. Perseus may never happen, and we need something now, not tomorrow, so Va would be a damn good start.

          • What will really be interesting is to see what missile the MOD will select as their ‘interim’ missile. As I understand it it will only go on 5 T-23s, and as they don’t have MK41 VLS, and as they probably don’t want to push the boat out, they will probably go for NSM, which although good, is very short ranged (it would be better on the T-31s for the littoral environment). They really need something with more distance, eg LSRAM or RSB-15. But I can’t see the MOD forking out for the LSRAM, especially as the USN isn’t using a canister launched version.

            Really we should update the Tomahawks and get some LSRAM for the P8s, which would immediately enhance our anti-ship capabilities ten-fold regardless of what’s put on the surface fleet.

          • What I mean is it would probably be cheaper from a defence planners perspective to expend them and buy replacements than upgrade them at a cost of probably $500k+ a missile due to low numbers involved and distance from factory. The total acquisition cost for the UK has historically been about twice the unit cost as other costs and services (such as spare parts, support costs, manufacturer supplied training, software etc..) will likely be factored in.

            The Mk3 cost was about $1.5m a missile in the 90’s, that gradually fell to a low of around $800k for a Mk4 around 2010 but through the last decade as production rate has declined and the Mk5 capability improvements were under development the cost has creeped up again to around $1.5m a unit for Mk4 between 2016-2018 and $1.8m for a new Mk5.

          • Yeah, I get that, but are they actually reopening the production line or just upgrading existing missiles? I think it’s the latter, but not sure.

    • There is no provision in US law that requires that US manufactured weapons or systems must be fielded in the US first. FMS is actually a specific program defined under the AECA and is so structured to distinguish it from Direct Commercial Sales (DCS). There are specific provisions about the export of US arms but fielding them in the US first is not one of them. There is nothing to prevent a US manufacturer from selling a weapon to a foreign government that it has not sold to the US military as long as the sale meets the provisions of AECA.

  4. A few comments today suggesting that the UK should purchase Block V Tomahawks and V-22 Ospreys for the RN, apart from already having acquired American F-35Bs, EC-135s and P-8s. I wonder whether, at some point, US Congress might surprise us and sanction the purchase of some British kit for their armed forces. It happened in the past with British aircraft being built under license (Canberra, Harrier and Hawk) but today, there is nothing designed, built or manufactured here that the Yanks would want.

  5. The Tomahawk is a good land attack missile. Its terrain following capabilities, low altitude and range means in most cases its not detected until the last minute. As an anitship missile I have my doubts as there no terrain to mask the approach especially high end assets that would be heavily defended. Perhaps against resupply ships, other lower end targets or littoral ares where terrain could be used to evade radar it could have an impact or if used in conjunction with EW aircraft.
