The M118 is an air-dropped general-purpose or demolition bomb used by United States military forces. It dates back to the time of the Korean War of the early 1950s. Although it has a nominal weight of {{convert|3,000|lb|kg}}, its actual weight, depending on fuse and retardation options, is somewhat higher. A typical non-retarded configuration has a total weight of {{convert|3,049|lb|kg}} with an explosive content of {{convert|1,975|lb|kg}} of tritonal. This is a much higher percentage than in the more recent American Mark 80 series bombs thus the designation as a demolition bomb.{{Citation needed|date=November 2023}}

In the late 1950s through the early 1970s it was a standard aircraft weapon, carried by the F-100 Super Sabre, F-111 Ardvark, F-104 Starfighter, F-105 Thunderchief, and F-4 Phantom. Some apparently remain in the USAF inventory, although they are rarely used today.

It was a component of the GBU-9/B version of the Rockwell electro-optically guided Homing Bomb System (HOBOS). This weapon consisted of an M118 fitted with a KMU-390/B guidance kit with an image contrast seeker, strakes and cruciform tail fins to guide the bomb to its target.{{Cite web |date=10 September 1970 |title=Second Generation Weaponry in SEA |url=https://apps.dtic.mil/sti/tr/pdf/ADA486715.pdf |access-date=22 January 2024 |website=DTIC |pages=38-42}} It was also used in the Texas Instruments Paveway series of laser-guided bombs as the GBU-11 when it was fitted with the KMU-388 seeker head, MAU-157 Computer Control Group and the MXU-602 Airfoil Group. This latter consisted of four fixed cruciform fins and four moveable canards to control the bomb's trajectory. It was also fitted with an AIM-9B Sidewinder infra-red seeker and an AGM-45 Shrike nose cone during 1967 tests at the Naval Ordnance Test Station China Lake, possibly in an attempt to create an infra-red guided bomb.{{Cite web|url=http://www.chinalakealumni.org/1967/1967mo.htm#thumb|title = 1967 China Lake Photo Gallery}} This was called the Bombwinder.

15 of these M118 Paveway Is were evaluated between 15 October to 9 November 1969.
