Military experts say several precision-guided weapons made by Tucson-based Raytheon Missile Systems are among those likely to be used in the expected U.S. and allied attack on the Syrian regime. Here’s a quick look at the weapons:

BGM-109 Tomahawk cruise missile

Launched from warships and submarines, the 18-foot long (20-foot with rocket booster) Tomahawk is the nation’s top long-range tactical missile and also is used by the U.K.’s Royal Navy. The Tomahawk was used at the outset of the wars in Iraq and Afghanistan to destroy air defenses and high-value targets.

It carries a payload of up to 1,000 pounds, with a reported range of 900 to 1,500 miles, depending on the version.

It uses inertial navigation, GPS satellite guidance and terrain-map and scene matching technologies for a claimed accuracy of within 10 meters. The latest version, the Tactical or Block IV Tomahawk, also can be retargeted in midflight.

• Cost: $900,000 to $1.4 million each, depending on version

AGM-88 High-speed Anti-Radiation Missile (HARM)

Designed to home in on the radiation from enemy air-defense radars and surface-to-air missile sites, the HARM may be used particularly if aircraft are deployed in an attack.

The 13-foot HARM flies at more than twice the speed of sound to reach targets at a range of about 70 miles.

• Cost: $284,000 each

AGM-154 Joint Standoff Weapon (JSOW)

Though unpowered, the air-launched, precision-guided bomb can glide up to about 80 miles when launched at high altitude; used in Iraq and Afghanistan.

The 13-foot JSOW uses GPS and inertial navigation (newer versions include an infrared target seeker) for accuracy within 3 meters. The latest, JSOW C-1 version adds a two-way data link for use against moving targets.

• Cost: About $395,000 each (Navy 2012 figures)
