The Sedena Henschel HWK-11 was a joint project between the Mexican defense secretary (SEDENA) and Henschel Wehrtechnik GmbH of West Germany.

Development

The HWK-11 came about at the request from the Mexican defense secretary for a new tracked armored troop carrying vehicle for the Mexican army. The HWK was mainly German designed although Mexico had some input in the design process in the form that Mexico set certain requirements and specifications for the vehicle and Mexico also designed the basic configuration of the hull.

Production

In 1964 the first 12 vehicles were manufactured in West Germany and delivered to the Mexican Army while facilities were set up in Mexico to manufacture the vehicle locally. Initially 350 HWK-11s were to be manufactured for the Mexican military but only 40 were manufactured in Mexico before production ceased in 1966 due to lack of interest from the Mexican government.

Specifications

First Version - 1965

The first versions of the HWK-11 were strictly troop transport vehicles with only a single turret mounted 7.62 MG3 machine gun that could be fired from within the vehicle. This initial version featured a 180 hp engine and a two image intensifiers, one for the driver and one for the machine gun operator.

Second Version - 1980

In 1980 the vehicle was improved by the NIMDA company with the addition of a turret similar to that used on the French AMX-10P but with more armor. This turret mounted a French M693 F1 20 mm automatic cannon, at this point the vehicle could now be considered a true infantry fighting vehicle (IFV). The upgrade also included the upgrading of the vehicles engine to the 6V-53 Detroit Diesel which produced 210 hp and allowed the vehicle to reach up to 70 km/h.

Third Version - 1993

In 1993 the vehicle was upgraded one more time, given a more powerful engine (the type of which is unknown) and new German made M113 caterpillar road wheels. The most significant upgrade to this new version is the addition of a fully enclosed turret mounting a computer controlled Rheinmetall MK 20 Rh202 20 mm automatic cannon.
