Overview
SA-35 is a 35 mm self-propelled anti-aircraft gun developed by PIT-RADWAR and mounted on a Jelcz 663.45 T60 (6×6) truck chassis, presented as an effector for engaging, among others, unmanned aerial vehicles, helicopters and aircraft ; it was first publicly shown at the MSPO 2024 as a demonstrator.
Design and integration
In manufacturer materials, SA-35 was described as a solution combining an artillery effector (the firepower of the AM-35), a programmable ammunition system, and sensors and a fire-control system based on an electro-optical channel (ZGS-35) and a radiolocation channel (TUGA radar), mounted on a mobile 6×6 "3rd generation" Jelcz platform.
Armament and ammunition
The main armament of SA-35 is the autocannon KDA-35 in 35×228 mm caliber. In publicly available materials concerning PIT-RADWAR 35 mm solutions, the following were indicated, among others: * KDA gun parameters: theoretical rate of fire 550 rounds/min, muzzle velocity up to 1385 m/s, engagement range against air targets up to 4000 m and against ground targets up to 2500 m ; * ammunition types (in descriptions of the 35 mm family): including FAPDS-T subcaliber and programmable ABM (Air Burst Munition) ; * barrel length: 3150 mm ; * gun weight: 675 kg. In the XXXII MSPO brochure, it was indicated that the gun is fully stabilized, which is intended to enable firing while driving.
Fire control system and sensors
The TUGA radar was described as an AESA 4D radar in the X band, intended, among other things, for detecting and tracking small air targets (including unmanned aerial vehicles) and supporting fire.
In publicly available manufacturer materials and descriptions of the OSU-35K/AM-35 family (on which the SA-35 effector is based), the following fire-control elements were indicated: * TUGA radar – a 4D radar with an AESA antenna, using FMCW technique; intended to detect and track, among others, unmanned aerial vehicles, aircraft and helicopters ; * ZGS-35K electro-optical head – a thermal imaging camera (3–5 μm), daylight camera and a laser rangefinder ; * FCS blocks – the BSKO-35K fire-control system block and the RSKO-35K backup fire-control station (described in the OSU-35K family as system elements) ; * stabilization – in the OSU-35K family description, stabilization of the sensors’ line of sight and the gun’s aiming line was indicated, enabling firing while moving (in maritime conditions).
In reports about the SA-35 demonstrator, the possibility of remote control (remote station/terminal) was also described.
Carrier (Jelcz 663.45 6×6)
In reports from MSPO, the demonstrator carrier was described as an armored Jelcz 663.45 T60 6×6 truck. In the demonstrator description, a turret mass with the gun of about 3500 kg and the mass of the complete platform (turret + fire-control system elements on a container platform) of about 6000 kg were given. ; * mass and GVW: curb weight "a little over 18 t", gross vehicle weight up to 33 t; with a trailer up to 57 t ; * cab: armored (indicated level 1 according to STANAG 4569), three-person; in the 3rd-generation layout the engine was placed behind the cab (the "powerpack" concept) ; * transmission: ZF automatic (6 forward gears).
History
In trade publications, SA-35 was placed within the line of Polish work on 35 mm artillery systems (the land thread "Noteć" and the parallel naval thread OSU-35/OSU-35K), with solutions derived from the OSU-35K/AM-35 family indicated as the effector. The system was publicly shown, among others, at MSPO 2024 in Kielce. In February 2026, PIT-RADWAR stated that SA-35 guns are to be used in the fire modules of the Armaments Agency-ordered SAN system.
