Lockheed Martin was awarded a contract to compete with Raytheon when there was a break in production caused by transferring manufacturing out of Texas. Raytheon production of the Paveway II is centered in Arizona, Texas, and New Mexico. Lockheed Martin production is centered in Pennsylvania. Laser-guided bombs are often labeled as "smart bombs", despite requiring external input in the form of laser designation of the intended target. According to Raytheon's fact sheet for the Paveway 2, 99 deliveries of guided munitions will yield a circular error
