Lockheed Martin AGM-179 JAGM

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

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.

Marines sink moving vessel at sea with new missile in Pacific training

The missile gives users better standoff and true "fire and forget" capabilities.
www.defensenews.com www.defensenews.com

The missile weighs about 114 pounds, is nearly six feet long and 7 inches in diameter, according to the company’s website. It uses a solid rocket motor and can carry a multipurpose warhead with a shaped-charge package inside a fragmenting case, according to the U.S. Navy Air Systems Command.

The weapon can be used on combat vehicles, air defense equipment, launchers, buildings, bunkers, patrol craft and command and control nodes, according to the command.

The Army also purchased the new missile to arm its Viper equivalent, the AH-64E Apache helicopter, Defense News reported.

I wonder if and when we'll see the AGM-179 being donated to Ukraine and used by them some time in the near future?

On a more practical level, is there a weight limit that two servicemen can lift, since Hellfire (and i can only assume JAGM) is manually loaded?

IIRC, the Military says 65lbs per dude.


===========
One odd note: All the pictures of JAGM show it with 3 HE bands on it, while Hellfire only has 2. Is that from a dual pulse rocket or something?

A lot of Hellfire pics have three yellow bands. Tandem warhead plus motor, I think.

In theory. But Hellfire at least has long had a yellow band at the head of the propulsion section. Don't know exactly why, but it is.

PS: Hellfires with two stripes probably have unitary blast-frag warheads instead of the tandem HEAT version.
 
So what is the most numerous variant of the Hellfire? Blast-Fragmentation or HEAT? Just a question that was annoying me. :confused:

Vast majority are HEAT, with limited numbers of blast-frag and thermobaric warheads. (The Swedish coast defense version was the origin of the blast-frag warhead).
 
I did not realise that the Swedish coast version was the originator of the blast-fragmentation warhead variant TomS, what was the purpose of the Swedish coast variant Anti-Ship?
