Lockheed Martin AGM-179 JAGM

That looks like it is a from a game of some kind.

The Army will plan on launching JAGM from its Gray Eagle platform no doubt

Any guesses on how far the missile will go if launched from ~18-20,000 feet, at say 150 knots? 350 knots?

 

[sferrin]

16km? Wasn't this supposed to finally give us a JCM? (Which was to have about 28km range.)

Brimstone is double even the latter at the same weight.

 

[Forest Green]

In fairness Brimstone doesn't have a tri-mode seeker though, and I think the warhead is lighter (7kg vs 9kg).

 

[Kat Tsun]

I think Brimstone's seeker can do radar imaging with the mmW seeker, though. It's not just a GMTI like Merlin or Wasp were.

 

[Forest Green]

Oh sure, but it isn't passive like IIR, and although very resilient to jamming, jamming is still presumably an option. Whether it would make any difference in practice is debatable.

The thing is MMW jamming really isn't that much of a thing just yet, and mere smoke screens are still the primary go-to counter measures against MMW guided munitions...

 

[FighterJock]

I thought that smoke screens would be useless against MMW guided missiles, it would take something like Chaff or ECM operating in the Millimetre wavelength to jam them would it not?

Some modern hot smoke has suspended metal particles or other things that interfere with MMW radar as well as infrared.

 

[Forest Green]

The tri-mode seeker just offers a little more versatility against jamming, but again, whether it would make any difference in practice is debatable. Brimstone has a very high Pk to date, very close to 100%.

Considering IIR in any band is significantly easier to jam than a 94 GHz imaging seeker, probably not...

Jamming in 94 GHz is barely a thing, it mostly happens by accident these days. Detection of 94 GHz emitter requires a strategic complex, or at least a operational complex, the kind you might find in a field army or a centerpiece escort of a naval surface task force. Partly this is because it's very high frequency and partly because it is very short range. This means that it has limited applications, but what applications it has would be widespread (potential targets), and it requires very expensive components.

The biggest/most obvious reason you'd use an IIR seeker with a mmW is if you can't produce 94 GHz/W-band imaging seekers cheaply, in which case you're using a 35 GHz for GMTI and target detection, and slewing the IIR onto it for contrast matching and target identification/verification.

Whether that's the case for Stormbreaker, I don't know. It could be that the IIR, in MWIR band, is simply used for naval/bad weather acquisition at range, which is another valid reason. Alternatively it is a "long-range" sensor with a large LWIR staring array that slews the mmW imaging radar. This would be the inverse of the 35 GHz-IIR setup and take advantage of the fact that LWIR can see about 5-8 km in atmosphere in good conditions (Arrowhead FLIR) in a form factor roughly the size of Stormbreaker, yet has poor resolution, and can be rather easily fooled at range.

The other obvious downside is that a trimode seeker leaves less room for each sensor physically, which makes them all slightly worse. The 94 GHz mmWi would have better performance than Stormbreaker's simply based on the fact that it is probably a larger antenna array.

Degraded performance of the MBDA mmWi seeker in coastal areas is not something that seems to bother the Royal Navy or RAF either.

Lockheed Martin's JAGM-MR Advances with Enhanced Tri-Mode Seeker

Los Angeles CA (SPX) Dec 07, 2023 - Lockheed Martin achieved a significant milestone with the successful guided flight test of the JAGM-MR (Joint Air-to-Ground Missile - Multi-Role) on December 2, 2023, at the China Lake Test Range in

Raytheon/Boeing Joint Air-to-Ground Missile (JAGM) Desktop Model and Patch

This is a new Desktop Model and Flight Jacket patch from the Raytheon-Boeing Joint Air-to-Ground Missile (JAGM)See below for a description but basically this was a joint venture with Raytheon and Boeing which had several successful flight test (firings). However Lockheed-Martin ended up winning the competition but this may still be a contender for future buys/competitions. The Model is made by Dimensional Technologies, Inc. Vista, California (stand is 8" x 5", model is 10" long) Both are brand new, model box only opened to take pictures The patch is 3 and 1/2 inches high by 4" wide.
