context_page_description: The Kingdom of Romania was a constitutional monarchy that existed in Romania from 14 March / 26 March 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I, until 1947 with the abdication of King Michael I of Romania, and the Romanian parliament proclaiming Romania a people's republic.
  From 1859 to 1877, Romania evolved from a personal union of two vassal principalities under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War, when it also received Northern Dobruja in exchange for the southern part of Bessarabia. The kingdom's territory during the reign of King Carol I, between 14 / 26 March 1881 and 27 September / 10 October 1914 is sometimes referred as the Romanian Old Kingdom, to distinguish it from "Greater Romania", which included the provinces that became part of the state after World War I.
  With the exception of the southern halves of Bukovina and Transylvania, these territories were ceded to neighboring countries in 1940, under the pressure of Nazi Germany or the Soviet Union.
context_section_description: Romanian military industry during World War I was mainly focused on converting various fortification guns into field and anti-aircraft artillery. Up to 334 German 53 mm Fahrpanzer guns, 93 French 57 mm Hotchkiss guns, 66 Krupp 150 mm guns and dozens more 210 mm guns were mounted on Romanian-built carriages and transformed into mobile field artillery, with 45 Krupp 75 mm guns and 132 Hotchkiss 57 mm guns being transformed into anti-aircraft artillery. The Romanians also upgraded 120 German Krupp 105 mm howitzers, the result being the most effective field howitzer in Europe at that time. Romania even managed to design and build from scratch its own model of mortar, the 250 mm Negrei Model 1916. Other Romanian technological assets include the building of Vlaicu III, the world's first aircraft made of metal. The Romanian Navy possessed the largest warships on the Danube. They were a class of 4 river monitors, built locally at the Galați shipyard using parts manufactured in Austria-Hungary, and the first one launched was Lascăr Catargiu, in 1907. The Romanian monitors displaced almost 700 tons, were armed with three 120 mm naval guns in 3 turrets, two 120 mm naval howitzers, four 47 mm anti-aircraft guns and two 6.5 machine guns. The monitors took part in the Battle of Turtucaia and the First Battle of Cobadin. The Romanian-designed Schneider 150 mm Model 1912 howitzer was considered one of the most modern field guns on the Western Front.
  The Romanian armament industry was expanded greatly during the Interwar period and World War II. New factories were constructed, such as the Industria Aeronautică Română and Societatea Pentru Exploatări Tehnice aircraft factories, which produced hundreds of indigenous aircraft, such as IAR 37, IAR 80 and SET 7. Before the war, Romania acquired from France the licence to produce hundreds of Brandt Mle 27/31 and Brandt Mle 1935 mortars, with hundreds more produced during the war, and also the licence to produce 140 French 47 mm Schneider anti-tank guns at the Concordia factory, with 118 produced between 26 May 1939 and 1 August 1940 and hundreds more produced during the war; these guns were to be towed by Malaxa Tip UE armored carriers, built since late 1939 at the Malaxa factory under French licence, eventually 126 being built until March 1941. Czechoslovak licence was acquired in 1938 to produce the ZB vz. 30 machine gun, with 5,000 being built at the Cugir gun factory until the start of Operation Barbarossa in June 1941. Romania also acquired the licence to produce the AH-IV tankette, but ultimately only one prototype was built locally. German licence was acquired in 1938 to produce 360 37 mm Rheinmetall anti-aircraft guns, but only 102 were produced until May 1941. British licence was acquired to produce 100 Vickers Model 1931 75 mm anti-aircraft guns at the Reșița works, with the first battery of 6 guns entering service on 1 August 1939, and 100 more guns were built during the war for a total production of 200. On 14 June, Romania launched the first locally-built warship, the minelayer NMS Amiral Murgescu.
  During the war, Romania copied and produced hundreds of Soviet M1938 mortars, as well as designing and producing up to 400 75 mm Reșița Model 1943 anti-tank guns. Infantry weapons designed and produced by Romania during the war include the Orița M1941 sub-machinegun and the Argeș flamethrower. Romania also built 30 Vănătorul de care R-35, 34 TACAM T-60, 21 TACAM R-2 tank destroyers and rebuilt 34 captured Soviet Komsomolets armored tractors. A few prototype vehicles were also built, such as the Mareșal tank destroyer, which is credited with being the inspiration for the German Hetzer, a Renault R-35 tank with a T-26 turret and an artillery tractor known as T-1. Warships built include the submarines NMS Rechinul and NMS Marsuinul, a class of 4 minesweepers, 6 Dutch-designed torpedo boats and 2 gunboats.
