I was able to look at the M270A1 up
close and personal at the last Mitchell National Guard Open House. I took
the time to photo detail the differences between the M270 and the M270A1.
The M270A1 is a conversion done at the factory. A company will receive the
new units and their old units are hauled back to the factory to be updated and
delivered to the next company.
The biggest differences between
the two units are internal. The launch platform is now elevated
hydraulically rather than electrically. This reduces the number of
batteries in the unit and greatly reduces the time used to go for traveling to
firing. The engine is also more powerful increasing its top speed.
The next big change is the targeting computer. The old unit measured
distance by counting revolutions of the wheels. This was fairly accurate,
but as the wheels wear, the accuracy goes down. The new unit uses GPS.
The new unit also has a full keyboard to enter information and is far more
versatile. Mission programming is also much simpler.
there are three differences I found. The first is related to the new
targeting computer. On the top of the rocket/missile turret there is a GPS
The other way
to tell between the two at a distance are these two bolted on plates directly
above the tow cable heads.
difference is at the base of the turret in the back. There are two large
grounding straps that are not on the M270. Although visible externally,
you can only see these while looking down into this area.
continue to study the pictures from the M270 and the M270A1. As I find
more differences, I will add them to the page. If anyone else has
information to add, please email
