M53/59 Praga
1950s self-propelled twin 30 mm anti-aircraft gun

The M53/59 Praga is a Czechoslovak self-propelled anti-aircraft gun developed in the late 1950s. It consists of an armoured version of the Praga V3S six-wheel drive truck chassis, armed with a modified version of the M53 twin 30 mm (1.2 in) anti-aircraft gun mounted on the rear, which can be removed and used to provide ground support.
In Czechoslovakia, it was known as Praga PLDvK vz. 53/59 (PLDvK Model 53/59). PLDvK stands for Protiletadlový dvojkanón, or "twin anti-aircraft cannon". Vehicles for the export market were sold under the designation Praga M53/59 "Ještěrka" ("Lizard").
Description
The M53/59 has an all-welded steel armoured hull with a front engine, crew compartment at the centre and rear mounted guns. The armour is sloped to provide protection against small arms and shrapnel without increasing weight.
Armoured covers with vision slits which can be lowered in combat to provide additional protection to the driver and commander, while the two loaders seated on the back of the crew compartment have two vision slits behind the side doors. The commander also has a hemispherical plexiglass cupola for observation.
This brief starts where responsible research should: with the source description of “M53/59 Praga” as 1950s self-propelled twin 30 mm anti-aircraft gun. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1950s self-propelled twin 30 mm anti-aircraft gun. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q1455616. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
