Aerospace Daily & Defense Report
Joint Common Missile's Demise Spurs 'Capability Needs' Study
By Marc Selinger

The U.S. Defense Department still seems interested in eventually developing a capability similar to the Joint Common Missile (JCM), despite a recent decision to kill the air-to-ground missile program.
While revealing plans to terminate JCM, DOD's Program Budget Decision (PBD) No. 753 directs the chairman of the Joint Chiefs of Staff to "determine the capability needs" to equip fixed-wing tactical aircraft, rotary-wing aircraft and unmanned aerial vehicles with "precision, air-to-ground, close-air-support weapons." The study is due to be finished in time for a fiscal 2008 budget review.
Canceling the Army-led JCM will save about $2.4 billion over the next six years, the PBD says. The PBD, approved Dec. 23 by Deputy Defense Secretary Paul Wolfowitz (DAILY, Jan. 4), contains a total of $30 billion in program cuts, part of a broader Bush Administration effort to curb federal spending.
Lockheed Martin, JCM's prime contractor, said in a statement late Jan. 3 that it has not been officially notified of any changes to the JCM program. It also said the missile's development effort has been meeting all of its goals.
In May 2004, Lockheed Martin was picked over Raytheon and Boeing-Northrop Grumman teams to conduct JCM's four-year system development and demonstration (SDD) phase, which was to be worth as much as $1.6 billion (DAILY, May 6). The Army, Marine Corps and Navy were planning to buy 54,000 missiles, which would have boosted the program's total value to $5 billion.
JCM was designed to replace Lockheed Martin's Hellfire and Longbow missiles, used on the AH-64 Apache, AH-1Z Cobra and MH-60R Seahawk helicopters, and Raytheon-made Maverick missiles used on the F/A-18E/F Super Hornet fighter. Fielding of the new missile was scheduled to begin in FY '09.
While DOD has declined to comment publicly on why it targeted JCM specifically, Steven Zaloga, an analyst at the Teal Group, told The DAILY Jan. 4 that several factors could have doomed the program, including the fact that the Hellfire and Longbow missiles still are relatively young.

Meatheads, the only good reason to cancel it is if we have vast quantities of the other missles in storage. The Hellfire has always seemed like a perfect match to the A-10 as well rather than the heavier, dragier Mavs. I think Hellfire is a good competitor to the Mav for armor but it cant match the big warhead version of Mav for anti-structure type targets (buildings, bridges and such) JDAM sure works though.

Hellfire has an Extreme limitation

Distance and Gimble Limits. (although the latest RADAR Hellfire has Inertial NAv)

The Maverick for the time being is the only A2G missile that provides the Envelope Freedom the Hellfire cant match.

"RickUSN-

That was intelligent and useful Mudd.

But it certainly is what Ive come to expect.

Mindless babbling with no intent to either enlighten or inform.

I thought I would see the JASSM get ax'd way before this project.

I got some good picture of JCM on a F/A-18c Hornet on this site

Imagine an A-10C loaded with this anti-tank missile. It wouldn’t need a targeting pod to fire it, since it has a tri-mode seeker and could lock on with the infra red mode just like the maverick is used today.
However the producer of the missile Lockheed and Alabama lawmakers are lobbing to save the JCM.

here is some more inforamation

March 15, 2005: The U.S. Army is canceling its JCM (Joint Common Missile) program, meant to develop a replacement for the Hellfire anti-tank missile. The 108 pound Hellfire , used by helicopters and UAVs, has been in service since 1985, and some 76,000 have been built. The JCM was becoming too expensive, and many officers believed that the existing Hellfire II and heavier (670 pound) Maverick and SDB (250 pound Small Diameter smart Bomb) covered all the missions the services need to handle. The demise of the JCM also spotlights the importance of the guidance systems for missiles, and the ease with which missiles can be upgraded with more effective electronics. The basic design of these older missiles is not likely to change any time soon, and any of the main components (structure, rocket motor, controls, warhead, guidance system) can be upgraded. While the idea of having a common air-to-surface anti-tank missile for all the services was attractive, it simply didn’t add up in the end. The navy and air force fighters can use a larger missile, and the Hellfire has gotten a new lease on life via use on small UAVs. JCM, while nice in theory, didn’t pan out in practice.
