these engines for the army.

Teledyne Vehicle Systems was acquired by General Dynamics (the main
contractor for the Abrahms Main Battle Tank and other vehicles) in
March, 1996:

(see Acquisitions section)

Now part of General Dynamics Land Systems (http://www.gdls.com), the
Propulsion Systems group manufactures and services the engines for the
M1 Abrahms line of armored vehicles. Their website is
http://www.defensepropulsion.com .

The most recent Army contract announcement involving the M1 Abrahms
was in May, 2003:

In this announcement, the General Dynamics Land Systems contract was
revised to include additional supply and maintenance work for the
upgrade of several M1A2 tanks.

General Dynamics provides depot services to supplement the unit-level
maintenance work performed by Army personnel themselves. More on this
can be seen in this 2002 presentation:
