Stormvogn m/39

== Design and Development ==
The inspiration for the design of the Stormvogn m/39 stemmed from the widespread use of German Self-Propelled Guns (SPGs) across Europe, which highlighted the value of swiftly deployable vehicles with enhanced speed and firepower. Recognizing the strategic advantage, the Royal Norwegian Army, facing budget constraints, sought a cost-effective solution to bolster the armoured capabilities of its Royal Cavalry Section. In response, Kongsberg Våpen og Stridsvogn Fabrikk embarked on the "Stromvogn" project.
Incorporating converted hulls and an open-top casemate instead of a conventional turret, the inaugural Stormvogn, the m/39, was equipped with the L/20.5 M/39 "Berghaubits," a modified 75mm mountain howitzer with an elongated barrel. Renowned for its prowess in infantry support and anti-tank operations, the Stormvogn m/39 was purpose-built for engagements against light vehicles, fortified positions, and infantry units.
== Combat History ==
Deployed extensively throughout the conflict, the Stormvogn m/39 proved its mettle in numerous engagements. Approximately 50 to 100 units were produced, reflecting its significant combat presence. From the early clashes in Narvik and Oslo to the decisive Liberation of Halden in 1944, the Stormvogn m/39 remained a stalwart presence on the battlefield.
== Variants ==
Adapting to evolving battlefield demands, the Stormvogn m/39 underwent several field modifications, while official updates were integrated in tandem with enhancements to its base chassis, the Panservogn m/39. Notably, in 1942, a comprehensive overhaul introduced the Stormvogn m/39 R-2 variant, featuring a revamped engine, expanded fuel capacity, and the introduction of the upgraded Kongsberg L/42 Stormkanon. This versatile cannon, boasting both 75mm and interchangeable 65mm barrels, significantly augmented the vehicle's combat capabilities.
The Improvised Tank Destroyer
Amidst the escalating conflict in late 1940, Forsvarsverkene pursued experimentation with a heavily armored iteration of the Stormvogn m/39. This endeavor birthed the Jegervogn m/39 (1940), a hastily crafted variant featuring a crude encased casemate, marking it as Norway's inaugural designated tank destroyer.
