There have been various proposals to develop a fire-and-forget successor to the TOW. An IIR (Imaging Infrared) seeker was tested by Texas Instruments in the early 1990s, but not adapoted. The FOTT (Follow-On To TOW) program, begun in 1996 as a design competition for a TOW successor, was cancelled without a result in 1998. However, efforts to develop a fire-and-forget guidance method either as an upgrade for existing TOW rounds or for new missiles continued, and at that time it is hoped that such a system may be ready in the 2005/2007 time frame. Beginning in 2000, Raytheon was developing the TOW-FF (TOW Fire-and-Forget), which is a TOW with an IIR focal plane seeker, and a wireless data link for optional command guidance. However, funding limitations led to the cancellation of the TOW-FF program in 2002.
