Im not sure about T-Lams ability to penetrate an IADS. and bump

Any idea what the change in dimensions is?

Found this:
RAYTHEON COMPLETES FREE FLIGHT OF JOINT STANDOFF WEAPON EXTENDED RANGE
NAVAL AIR WARFARE CENTER WEAPONS DIVISION SEA TEST RANGE, Calif., Nov 02, 2009 /PRNewswire via COMTEX/ -- Raytheon Company (NYSE: RTN) and the U.S. Navy completed the first free-flight demonstration of the Joint Standoff Weapon Extended Range air-to-surface precision guided missile.
The JSOW-ER is a powered variant of the combat-proven glide JSOW. It takes the GPS-inertial navigation system reliability of existing JSOW variants and combines it with the network-enabled maritime-interdiction capabilities currently in development for the JSOW C-1. The JSOW-ER also integrates the Hamilton-Sundstrand TJ-150 engine, currently in production for Raytheon's Miniature Air Launched Decoy.

"JSOW-ER will provide the warfighter with a powered spiral of JSOW C-1, extending the range of the weapon from 70 nautical miles (81 statute miles) to 300 nautical miles (345 statute miles)," said Harry Schulte, vice president of Raytheon Missile Systems Air Warfare Systems' product line. "Because JSOW-ER has the same outer mold lines and mass properties of the glide JSOW, it can be integrated on any aircraft capable of carrying glide JSOW. The cost of integration is negligible and the impact is reduced."

Question... If it has the same mass properries as JSOW does that mean the latter had ballast built in in anticipation of a future engine upgrade?

The fuselage is square but the unitary warhead is round, so the fuel could be placed around the warhead. Or maybe the warhead itself is smaller.

JSOW-ER was a Raytheon funded endeavor. Does anyone know if any military service is planning on purchasing the JSOW-ER?

Also, is the JSOW considered to be stealthy at all? Given that it was originally a glide bomb, and that the Hamilton Sunstrand engine only puts out 150lbs, I don't think it is attacking ala T-LAM via nap-of-the-earth flying, but rather the engine is just extending its range either on a very extended, very shallow ballistic arc, OR cruising at a given altitude until it arrives at its target and noses over for the terminal dive / attack maneuver (which I am guessing is probably ballistic in nature).

Which leads me to my next question, if JSOW / JSOW-ER is NOT NOE / high-g terminal maneuver capable, would it be susceptible to being intercepted by an advanced IADS?

Bloody Hell no wonder stuff cannot be found as JSF/F-35 info is moved ELSEWHERE on this forum - BAH HUMBUG!

viewtopic.php?f=38&t=24176&p=255531&hilit=affordable#p255531

Good way to fragment perfectly good F-35 information to put it elsewhere.

LO was a design consideration. Also note that it's a networked missile with all that implies in terms of being able to prosecute a target with the best chance of success.

http://www.deagel.com/news/Raytheon-Dem ... 01536.aspx

The engine ground test of JSOW ER successfully evaluated a flush inlet design and overall engine performance and showed that engine performance matched simulation results. The inlet will maintain the missile's excellent low observable characteristics.

Forgot about the JSM as it's got NOE/land attack modes also.

If you get real close to one, you'll notice all the gaps in the panels are filled in with some sort of ceramic material. So it's definitely designed for stealth. I'm not revealing anything as one can see them up close in many museums.

It's very clear that JSOW is very stealthy design and would be very difficult target for AD systems. It has shaping that would direct radar waves away from threat radar and surfaces look like they are made from material with low radar reflectivity. With no engine it has very low IR signature and even JSOW-ER has so small engine that it doesn't matter much. Engagement ranges for defensive systems are likely very short and even then several simultaneous JSOWs will likely overwhelm the defenses quickly.

JSOW has nose chines and serrated edges on the first joint.

I would not be surprised to find out it had some 1st gen RAM, but that's pure conjecture.

You can see even in this image that the joints are filled in with some material. When I took a close look at one, it appeared to be some sort of permanent ceramic-looking material.

Since this is a weapon, meaning pieces of it will be left over in the enemy's territory, I would think they aren't using RAM or something which would give technology to an adversary. Maybe earlier generation RAM paint.

Here is a Hi-Res side profile of a JSOW. Note how none of the panels lines are perpendicular or join at a 90 degree angle.

Link only as it's a large image.

If this is the case, why are the fasteners not covered over with a similar type of RAM putty? Would not the fasteners need to be covered over? Or would that be one of the last things they would do before hanging the munition on an aircraft? (Similar to they way they would butter the F-117s before a mission?)
