Mastranaza M-114 SPAA
Notes: This odd
vehicle has an interesting history.
In 1978, El Salvador took delivery of 27 used Woodmaster tractors – essentially
M-114s stripped of their armor and rebuilt as agricultural tractors.
Mastranza in El Salvador immediately got to work on them, re-plating them
and otherwise trying to get into working order.
They produced three variants: an APC (which US officials at first mistook
for an M-113, as the El Salvadoran APC looks quite similar at first glance), a
sort of gun carrier with a turret armed with several machineguns pointing in
several directions, and the AAA vehicle.
It is believed that no more than four of these vehicles have been built.
The biggest
problem that Mastranza had was the engines.
The Woodmaster does not have the same engine as the M-114 – it used a
different engine, a Chevy V-8 gasoline engine that produces 160 horsepower.
The gasoline engines were limited in range, unreliable, prone to
breakdowns, and tended to overheat when used in their new role in armored
vehicles. Within a year, Mastranza
replaced those engines with 134-horsepower LDT-465IC V-6 diesels adapted from
M-35 2.5-ton trucks. Though the
range was improved, speed was decreased, the engines are considerably heavier
than the gas engines, and the engines still regularly overheated.
This means that the M-114 SPAA (I don’t really know what else to call it)
is primarily a reaction or static support weapon rather than being able to keep
up with most vehicle convoys to support them in a dynamic roles.
The M-114 SPAA
has faces built up with thin armor plate; they are sloped on both the front and
sides. There are seats for the
driver and commander at the front; these have slits with windows at the front
and hatches above them. At the rear
is what looks like a ridiculously-large turret, housing a Yugoslavian-built
M-55A2 triple-20mm autocannon system (which uses three M-52 autocannons); this
system uses manual traverse and elevation.
The turret has no back at all.
