Abstract
A retrofit digital electronics unit replaces the analog electronics unit of a tube-launched optically-tracked wire-guided missile. The retrofit digital electronics unit is smaller in size permitting the warhead of the missile to be enlarged. Additionally, the retrofit digital electronics unit is more susceptible to modification through simple changes in software.
