Puola on moddannu PT-91 Twardyn
The PT-91M2 is a further upgrade of the PT-91 Twardy,
The PT-91M2 is an upgraded variant of the Polish PT-91
Twardy tank, although some sources suggest that the T-72 left in Polish Army service might be upgraded to this new configuration. Unlike the Polish Army PT-91 model, the PT-91M2 makes used of the Sagem SAVAN-15 fire control system from the French manufacturer Safran. This is also used on the Malaysian PT-91M
Pendekar, currently the most advanced PT-91 version in service with the military of a nation, and is related to the SAVAN-20 system used on the French Leclerc MBT.
The system consists of a new primary sight for the gunner, a ballistic computer and sensors for the gun stabilization and automatic lead. The gunner's optic with two axis stabilization includes a direct daylight optic with 2x and 10x magnification, a thermal imager with two magnification levels and electronic zoom, aswell as a laser rangfinder. According to the manufacturer, the SAVAN-15 fire control system offers a high accuracy with a first-round hit probability of more than 90 percent and can also be used to fire at moving targets while the tank itself is moving.
PT-17
A more severe upgrade for the T-72 and PT-91 designs is the new PT-17 main battle tank. This tank is the result of a closer cooperation between a number of Polish and Ukranian companies. While the hull seems to be still largely based on last year's PT-16's hull, the PT-17 features a new turret compared to its predecessor.
Borzuk
The Borsuk is a new infantry fighting vehicle currently being developed for the Polish Army by OBRUM.
First 3D renderings of the design already found its way on the internet last year. At MSPO 2017 the first prototype of the Borsuk (Polish for
badger) IFV was presented to the public for the first time. The new vehicle is meant to replace the Soviet-designed BMP-1s (locally known as BWP-1) in the Polish military.
The Borsuk is one of the few modern IFVs designed with amphibious capabilities, using two sets of water blades for propulsion in water. This key requirement of the Polish Army affects all other aspects of the vehicle's design. The Borsuk has a rather larger hull with a larger UFP and a relatively high roof height, in order to provide enough buyoancy for swimming through water. Moreover the weight of the vehicle is limited to only between 24 and 25 metric tons in the amphibious configuration. In order to achieve a lower weight, the vehicle can be fitted with rubber band tracks, which save about one metric ton of weight compared to conventional steel tracks. The Borsuk is fitted with the unmanned ZSSW-30 turret from HSW, which provides further weight reductions compared to a manned turret. The vehicle is manned by a crew of three (commander, driver and gunner) and can transport a six men infantry squad.
