BAE Tests New Smart Munition


BAE Systems and United Technologies Corporation recently completed a successful guided flight test of the Multi-Service Standard Guided Projectile at White Sands Missile Range, New Mexico.

The MS-SGP was fired from a 5-inch 62-caliber Mk 45 Mod 4 Naval Gun System and all guided flight test objectives were achieved, test officials maintain. The guided flight test, culminating more than 110 MS-SGP subsystem tests, demonstrates the tactical capability to a range of 38 kilometers.

The MS-SGP’s maximum range is nearly 100 kilometers, with accuracy of less than five meters. The MS-SGP significantly enhances the capability of U.S. Army and Marine Corps field artillery and U.S. Navy Mk 45 gun systems.

BAE Systems is no stranger to precision-guided munitions. It began working on the highly successful, but expensive Excalibur 155mm artillery round in the early 1990s. Excalibur has a range of about 40 kilometers and can be guided by GPS to within five meters of a target.

 The Multi-Service Standard Guided Projectile is designed to provide a single solution for responsive, tactical fires for addressing stationary or moving targets for multiple U.S. or allied services at a fraction of the cost of current alternatives.

“Currently the U.S. and its allies are using significantly more expensive solutions to address fire support and tactical targets,” Chris Hughes, vice president and general manager of Weapon Systems at BAE Systems, said in a press release. “The projectile can provide the U.S. forces with an affordable, long-range, and precision gun-launched projectile to greatly expand our fire support capability.”

The MS-SGP is scheduled to be fired from an M777 towed howitzer late this summer.

    We must not use this smart munition.. Just reading about it is harming innocent civilians in Pakistan. Put it on the shelf with the drones.

    • wpnexp

      First we have never used artillery across the border with Pakistan from all the reports I have heard from. Second, I suppose you think a barrage of unguided artillery would be better then. Or do you think we shouldn’t actually fight against bad guys, just let them go on killing wantonly? Now, innocent civilians are getting killed for two reasons only. Either they are supporting their terrorist families, and are harboring them in their homes or, the terrorists are forcing them to stay with them in order for civilian casualties to occur.

      • JJ6000

        ….or, the CIA simply made a mistake and bombed the wrong target. Example: an unreliable source provides info on a target which is not properly assessed and happens to be a bakery. So, who’s fault is this? The local militants or the people responsible for target selection i.e. the CIA?

        Pretending that things like this don’t happen is incredibly ignorant. With sustained military strikes mistakes get made and acting like the CIA should have zero responsibility for their mistakes is truly outrageous.

        • RunningBear

          Those that allow criminal acts by their neighbors are held responsible by the artillery round +/- 5 meters. Don’t tread on me….I bite back! :)

          • Bruce

            Does that rule apply to US citizens as well?

        • Josh

          Total number of civilians killed in US drones strikes so far in 2013: 0

          • JoeSovereign

            Number of US Citizens targeted for Illegal Summary Execution by Drone strike that have been publicly admitted by the US Government since 2009: 4

        • Free America

          You just made up a fake scenario and then claimed we are ignorant for not knowing it happens.

        • JoeSovereign

          It is just not mistakes. The US Government does not even acknowledge that the wives and children of suspected terrorist are collateral damage. They excluded from both the target list and the collateral casualties list. We routinely murder entire families because we believe a single member of a family is an enemy of the United States.

          I am not against Drone Strikes but nobody should lose sight of how ugly a practice it is.

      Your confusing the policy with the munitions.

      “Just reading about it is harming innocent civilians in Pakistan”

      Seems to me “hibeam” is being sarcastic.
      You know, saying something outlandish but meaning the opposite.
      Not that there aren’t fools out there who don’t realize the better out weapon systems, the better we are able to reduce civilian causalities.

      Are your panties binding HiBeam?

    • STemplar

      The ignorant savages being brain washed in the various madrasa in Pakistan are far more dangerous to Pakistani civilians than US artillery.

    • joe

      low beam you must have never had to call for fire before.

  • Bunny dicks

    Hell yea NSFS


    I like how this projectile is being given to the US military, but nearly all the measurements given to us in this article are in metric………

  • wpnexp

    The question that I have are, how is it adapted to different caliber rounds, and how does the round get to 100 km?

  • brownie

    The Chinese DEFEATED India in ’62 in artillery duels at high altitude. The greatest # of casualties in WWII were the result of artillery and assorted tubed weapons (over 60%).

    • green

      That’s not true. The Chinese defeated India in 1962 border war primarily through surprise, sound tactical maneuvers, and a disciplined, proficient ground force.

  • brownie

    General Ridgeway stopped the Red Chinese Army (800k) onslaught in Korea in ’51 by establishing 3 defensive artillery lines during the winter break in major hostilities. Artillery was the KEY in enabling the U.S. to stabilize the UN lines and stop the Red advance. From ’51 to ’53 there would be little movement.

    You are a dumba–, smart munitions are the way to go. That is unless you are one of the individual’s that’s using a school or a hospital as a shelter and fire on our troops from those locations. You might want to change your user name to low beam.

      Rob, you need to learn how to read the whole comment, not just the first half sentence. You must be government management someplace!

  • SJE

    Smart technology to save lives at low cost. Of course Lockmart is not involved.

  • hibeam

    Why do we need guided artillery when we have misguided apologies? We are sorry. That should be enough.

  • Tribulationtime

    Re$earch, all is Re$earch stupid!. They build the Xcalibur, and they have again all the way up. A $hame!!

  • Lance

    So we working on laser guided artillery.

  • JoeJFO

    As a 13F20L7 w/ 6 years in service, I can tell you the copperhead was a steaming pile of junk that was way overpriced. excal on the other hand, was awesome stuff. I often miss being in, if anything else to play with the new toys and being able to work with my joes.

    I wish this website had at least one credible dev/mod who would police up you bullsh*t posters from degrading this thread’s original topic into one more political blame game of international conspiracies.
    What could’ve been a great discussion has been reduced in the extreme to childish diatribe of “my country led by its evil corrupt wicked political system can beat up your country led by its evil corrupt wicked political system”.

    Stay on topic, please.

    Miss distance at 36km: 1.5m. Nice.

  • ohwilleke

    Is there a price tag for the rounds? Based on prices for similar munitions, I’d expect a price per round in the low five figures, but a lower price from standardization would really be a big deal.

    • d. kellogg

      Contrary to hopes of lower costs, these guided rounds that have to be built tolerant of the cannon launch stresses are still expensive: Excaliburs curbed at just over $100K each when ordered thru Federal Logistics Sources within the last year.
      But, as production rates increase and manufacturing processes are leaned down, the cost will drop (in the long run, the savings is also recognized thru reduced barrel wear on artillery because fewer PGMs can be fired in place of the massed fires and barrages of numerous unguided shells).
      The key that might keep the AGS’ 155mm LRLAP price down more favorably (seeing as it’s currently just a niche weapon on what few Zumwalts the USN will get) will be how many of the components (and manufacturing processes) can port directly over to the 5inch munition.
      Otherwise, missiles built on established production lines with known, proven tech, will still compete for price.

    • JCitizen

      It would be interesting to see a cost breakdown of what one howitzer round like that costs in comparison with the way it used to be done with six howitzers, (or maybe a battalion), with full crew, and shooting hundreds of rounds to kill the same or similar target. Of course they had to get closer too, so then you have to figure in counter fire losses of personnel and equipment. Attrition can get very expensive very fast.

  • Brian B Mulholland

    A five-inch round makes perfect sense for Naval use, but the last time I looked, the Army and Marines were not fielding howitzers in the 120mm or 125 mm. sizes. Will this round be fitted with a sabot to permit its’ use in 155 tubes?

  • That is, I believed in you, in everything you SAID you stood for, even while you were simultaneously chewing me to pieces (like right out of John Lennon’s “Working Class Hero”);

    as well as having been one of the most unique paradigms of obediently-humble submission

    you dare now call “insubordinate,” just because I’ve FINALLY HAD ENOUGH, AFTER

    HALF-A-LIFETIME, of being SNEERED AT, therefore, and if

    only so much MORE GUTLESSLY as well as PREDOMINANTLY BEHIND MY BACK, as a PUSSY and

    a KISS-ASS, even by my so-called “peers,” let-alone


    Finally, for now at least, if you cannot bring yourself to congratulate

    me for my candidness, I still like at least what you appear to

    be enough to hope you’ll not feel too indignantly or just plain dismissively and mockingly

    repulsed. , Icecap has 8 of the 11 scientists associated with it).

      The new round is an exciting and useful development.
