Tomahawk Re-routes Faster to Hit Moving Targets

tomahawk3A Navy destroyer recently test-fired a Block IV Tomahawk missile that quickly received updated target information in-flight, changed course rapidly  and destroyed a moving target, Raytheon officials said.

While the net-enabled Tomahawk Block IV missiles already have an ability to be re-targeted in flight, this Feb. 19 missile test aboard the USS Sterett demonstrated that the weapon can perform this function much faster, more frequently and with greater radio throughput, Raytheon officials explained.

“Typically the communications with Tomahawk are very deliberate.  With a higher radio throughput, you start sending the transmission repeatedly and the weapon just receives it,” said Chris Sprinkle, Tomahawk growth program manager, Raytheon.

The advantage to this kind of command and control information speed increase is that it improves the weapon’s ability to track, follow, adjust to and destroy moving targets over land or water, Sprinkle explained.

“We were looking at targets that may be mobile or moving over land or sea – to hit these types of targets you need to be able to send very rapid inflight target updates,” he added.

Thus far in combat, re-targeting Tomahawk Block IV missiles in flight has typically been a one-time event, Raytheon officials said. This newly demonstrated technological capability could make this much more frequent and expand the target set for the weapon.

During the test, the Tomahawk flew in sea-skim mode, meaning it travelled along the surface of the ocean while tracking its target and receiving in-flight updates.

So far, Raytheon has delivered 3,000 Tomahawk Block IVs to the Navy. The weapons are expected to have a service life of 30 years. Since the original initial operating capability of the Block IV weapon was 2004, many of them will be brought back at the 15 year service mark for re-certification during the 2017 to 2019 timeframe, said Roy Donelson, Tomahawk program director, Raytheon.

Raytheon plans to upgrade the missiles during this-recertification period and install new sensors and new communication gear so that the weapon has improved technology.

Donelson and Sprinkle explained that Raytheon is working on new passive and active seeker technology for the Tomahawk which would even better enable the weapon to discriminate between targets and destroy moving targets.

A passive seeker would receive an electromagnetic signal and follow it, whereas an active seeker would also have the ability to send out or ping an electronic signal and bounce it off potential targets. Raytheon is planning additional testing for its new seeker system on the weapon, which would allow it to separate legitimate from false targets while on-the-move.

Tomahawk missiles are a high-speed, low-altitude weapon designed to evade enemy air defenses – in part by flying lower to the ground and using precision GPS navigation systems.

They were originally developed as a Cold War weapon to go against sophisticated Soviet air defense systems by flying close to the terrain.

The Block IV missiles not only have the ability to re-route while in transit to a target but they can also send back real-time images of strategically vital areas and help conduct battle damage assessment.  The Block IV missile is also able loiter over targets as needed and receive targeting information from a nearby unmanned aircraft system.

In addition to GPS, Tomahawk Block IV missiles also have a camera-based navigational system called digital scene matching and correlation. They have anti-jam GPS receivers and inertial measurement units as well so as to ensure the weapon could function in a GPS-denied environment.

U.S. and British commanders fired 221 Tomahawk missiles in 2011 from warships at the outset of the attack on Libya and Moammar Gadhafi. The missiles struck about 20 sites and helped destroy Libya’s air defense system.

Many believe the threat of Tomahawk missiles from Navy destroyers off the coast of Syria were a huge part of what motivated the Assad regime to agree to the destruction of chemical weapons stockpiles.

Each warhead weighs about 3,500-pounds, costs about $569,000 and is 18-feet long with an 8-foot wingspan. Existing Tomahawk warheads include a 1,000-pound unitary warhead and submunitions dispenser variant carries which releases 166 combined-effects smaller bomblets, service officials said.

    Another contractor tor make work program to keep those retirement jobs sweet. Operationally there is no requirement. There aren’t any mobile targets that need to be hit by a large slow warhead.

    • exnuke

      You mean, like ships?

    • hibeam

      Is that the USS Choom Wagon in the picture?

    • Deuterium2H

      Besides the stupendously OBVIOUS (hint: naval vessels!!)…how about mobile SAMs, mobile Ballistic missiles, mobile Radar and other A2AD systems. Are you for real, Oblatt?? Or do you just pretend at being a first class ignoramus?

      Except if they didn’t have the capability you would complain that the are not able to attack real military targets.

      tomahawk basically has d same speed as the new LRASM (subsonic speed) so what makes it slow compared to other antiship missiles that we r using and planning on making?

      • blight_

        It’s slow like a Harpoon.

        The Russians love high-speed missiles, even at the expense of effective range.

  • hibeam

    What a waste of free phones money.

  • hibeam

    Now we have a Tomahawkerpoon missile. Maybe we can turn the Harpoon missile into a Harpoonahawk. That’s money well spent.

    The photo is a cruiser, the story talks about a destroyer.

    Why can Tomahawks upgrade to hypersonic……

    • Mastro

      Its not a supersonic platform- let alone hypersonic.

      Also- they need to be able to do hypersonic for more than 30 seconds over Edwards.

    • Raraavis

      There are supersonic stealth Tomahawks but they are classified.

      The military doesn’t like to talk about using 20 million dollar missiles to blow up a hut containing 5 guys in a robes and sandals who have never seen the inside of a school and posses about $350 dollars worth of small arms.

      • ajspades

        Talk about a straw man. These would be used against centers of mass like communications, power, SAM sits, and other infrastructure.

      • George

        that might be building small bombs that blow up U.S. Military personnel?

  • Taylor

    If you’ve seen one Oblatt2 comment, you’ve seen them all. Greedy contractors and we already have all the weapons we will ever need.

    • John Deere

      We have “all the weapons we will ever need”?

      It is apparent you have no idea how weapons technology evolves.

      If you rest on your laurels for a moment expect to lose the next war.

  • RRGED

    So this technology can justify hitting the wrong target mid flight?ooops wait a second I change my mind! LOL

  • JohnnyRanger

    Sooo….Tomohawk is an anti-ship missile again?

  • Yeast Infection

    So they made it do something that they say it can already do. How exciting. Look out China, we’re always two steps ahead of ya!

  • anthony bauwens

    Hope we never have to use them….

  • DennisJP

    There enabling this weapon to be better then the Chinese Anti- Carrier weapon. Just needs to be super sonic or better.

    • blight_

      The Anti-Carrier weapon is playing at an entirely different level. The PLA’s carrier-killer has incredible /range/ and is intended to drop a carrier dead well before it can launch a single aircraft or its escorts can fire a missile at its launcher.

      A low RCS version of the Tomahawk should definitely be considered. After Have Dash, all work on low RCS missiles simply stopped…at least in the public.

      Curious if work on a low-RCS version of various missiles is in the works. A VLS TLAM would be a potent weapon to throw at an enemy fleet, and if sea-skimming and small enough, could hit a target before radar picked it up and started putting CIWS lead into the air.

    They don’t make public all of the really awesome tech they are developing and delay the enemy’s ability to develop countermeasures.
