The M901 ITV (Improved TOW Vehicle) is a United States Army armored vehicle introduced into service in 1979, and designed to carry a dual M220 TOW launcher. It is based on the ubiquitous M113 Armored Personnel Carrier chassis.

The M901 ITV provides the crew and weapon system protection from small-arms fire and artillery fragments. The squad leader has a 270-degree range of view through the squad leader's periscope (SLP). The turret launcher has the capability for day and night acquisition and tracking of targets, and it provides firing coverages of 360 degrees in azimuth and +35 to −30 degrees in elevation. The ITV has stowage provisions for tripod-mounted TOW components configured so the ground system can be dismounted and set up in three to five minutes. In addition, the ITV is completely amphibious and is air transportable.

It has the following characteristics:

-A hydraulically and electrically powered "hammerhead" turret, attached to a modified M27 cupola, that can be operated manually.
