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.

        ….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.

      Your confusing the policy with the munitions.

        Guys ya’ll realize 90% of his post are random ramblings that don’t even make sense right?

      “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.

    • Corps-FO

      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

    • Belesari

      Well not so much. 5in are fine for unprepared targets but aren’t all that powerful other wise. We need something like the 8in Mk-71 gun for NGFS.

      I don’t think some people know what either of those terms mean


      Naval Gun Fire Support


      Near Shore Fire Support.


    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!

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


      Lock”mart” (suppose to be heed, but ya’ know) is more aviation, so.

      • SJE

        Why do we tolerate ripoffs from aerospace contractors but not others?

          Solyndra ring a bell?

  • 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!!

    • JoeSovereign

      Are you saying we should have stopped all research after Xcalibur the sword? Because that is how quickly your weapons will be outdated if you stop all research.

      • blight_

        Indeed, not sure I would want to go up against the PLA with javelins and slings either.

  • Lance

    So we working on laser guided artillery.

    • STemplar

      Called Copperhead, we’ve had it for decades.

      • d. kellogg

        Not as many were produced as some people may think, and they were very expensive, much more per round than Excalibur if we adjust for inflation (actually, I think just in sheer dollar value of its day, Copperhead was over $100K/shot…)

        Seeing how many recent GPS-guided munitions have been fitted with a laser seeker to allow greater precision at target, it will be curious to see if future block increments of Excalibur, even this 127mm weapon, come full circle and gain a laser seeker built around the much more reliable technology of today…

        Next step, as the tech base matures, is to develop a similar guided round suitable for 105mm artillery (not tank guns).

  • 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.

  • 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).
