During World War I, the Kingdom of Romania was a source of various types of military equipment. Either directly, or indirectly through Romanian-born people designing military equipment abroad.
Between 1914 and 1916, 59 Romanian factories along with numerous private contractors produced a total of 400,000 artillery rounds and 45 million small-arms cartridges. Added to these completed projectiles there were cartridge components (70 million bullets and 110 million primers) and artillery shell components (250,000 fuzes). Three Romanian factories produced 1.5 tons of explosives daily, and grenades were also manufactured. [1] Daily production of ammunition amounted to one cartridge for every rifle and two shells for every gun. [2] [3] When it joined the Great War in August 1916, Romania had a total of 600,000 shells. The Romanian Army had enough ammunition for its rifles to last five months, but the country needed 500,000 shells per month to avoid being overwhelmed. From France, 400,000 more shells were awaiting delivery. [4] The entire Romanian production of artillery rounds amounted to 400,000. [1]
At the beginning of the war, the Romanian factories in Bucharest were producing small quantities of ammunition, mostly for training purposes. Made of cast iron, these old models had low striking power. After the start of the war, following the huge amount of ammunition usage observed on the Western Front, production was focused on 75 mm (3.0 in) and 105 mm (4.1 in) quick-fire shells, but production remained limited and shells remained of poor quality. Such was the quality of Romanian-manufactured shells that during the Battle of Nagyszeben (Sibiu) – a Romanian defeat – percussion fuzes exploded inside gun barrels, killing and wounding gunners, or would not explode on the target. [5]
As elsewhere, in order to create new artillery units, the Romanians resorted to disarming their fortifications, a decision prompted in part by the quick German destruction of Belgian forts in 1914. By August 1916, part of the 1,400 guns and howitzers from the Romanian forts (37 mm (1.5 in) to 210 mm (8.3 in)) had been mounted on Romanian-produced carriages and assigned to field service. Some were converted to anti-aircraft guns. [6] For instance, the Romanian officer Ștefan Burileanu invented an effective anti-aircraft system for the Hotchkiss 57 mm (2.2 in) rapid-fire gun. [7] [8] Up until Romania's entry into the war, the focus was on light and medium guns. Between 1914 and 1916, 332 gun carriages were produced for guns up to 75 mm. During the same time period, 1,500 caissons were also produced. [1] After Romania entered the war, however, the heavy pieces were also turned into field guns. The 150 mm Krupp M1891/16 L/25 is one example. According to one photography dated October 1916, at least five such guns were converted for field use. Seven new heavy artillery regiments were formed. By 1918, the heaviest Romanian fortress guns had been converted for field use, as exemplified by the Iași (Krupp) Model 1888/1918 210 mm howitzer. [9]
The first artillery panoramic field lenses, later adopted by all the armies of the world, were invented by the Romanian General Toma Ghenea. [10] Ghenea patented his "sighting attachment for ordnance" on 13 December 1902. [11] Beginning with 1902, the panoramic sight began to gain ground very rapidly. But by 1907, Ghenea's was still "one of the most perfect yet devised". It had compensating gear for drift-caused lateral deviations and level of wheels. [12] Ghenea's gun sight enabled sighting adjustments to be made rapidly, even for extreme alterations. [13] The vertical angle which the sight made with the axis of the gun could be read on a quadrant scale. [14] The Ghenea sight was peculiar because the pedestal itself was mounted on a transverse horizontal pivot to which the drum on which the elevation was set was attached. The pedestal itself was always perpendicular with the line of sight. The longitudinal level was just over the eyepiece of the panorama sight. In the Romanian Army, Ghenea's sight was fitted to the 75 mm Krupp L/30 field gun, being used for both direct and indirect laying. [15] The Ghenea sight allowed the gun layer to adjust the range during the return of the piece in battery, by lightly turning the elevation screw which was just in front of him, without having to take his eye off the level. The bubble of the level was brought to its central position as soon as the forward movement of the gun was finished. With an ordinary sight, changing the range elevation while the gun was in motion was impossible. [16]
Between 1907 and 1908, Romania assembled and launched four river monitors at the Galați shipyard. The monitors were built in sections by STT in Austria-Hungary, then transported to Galați and assembled there. The four vessels were named Ion C. Brătianu, Lascăr Catargiu, Mihail Kogălniceanu and Alexandru Lahovary. Each vessel displaced 680 tons, had a top speed of 13 knots and a crew of 110. Armament consisted of three 120 mm (4.7 inches) L/35 naval guns, two 120 mm (4.7 inches) L/10 naval howitzers, four 47 mm guns and two 6.5 mm machine-guns. Armor thickness amounted to 75 mm (almost 3 inches) on the sides, deck and turrets and 50 mm (almost two inches) on the conning tower. All but Alexandru Lahovary were launched in 1907, the latter being launched in 1908. [17] [18] [19] The first monitor to be launched at Galați was Lascăr Catargiu. [20] The four monitors first saw action during the Battle of Turtucaia. On 2 September 1916, after the German formation known as Abteilung Kaufmann penetrated into the western edge of the defences of Turtucaia, the artillery fire of the Romanian monitors brought the Germans to a halt. The Abteilung attempted again on the following day, 3 September. It divided into three columns and attempted to seize high ground which dominated the Romanian defences. All three columns were brought to a halt by defensive fire, however, and then forced to withdraw, leaving behind around 300 dead and wounded. The third and final attack of Abteilung Kaufmann, on 4 September, was successful, the valuable high ground being captured. [21] Subsequently, the monitors proceeded to evacuate Turtucaia. Alexandru Lahovary evacuated General Teodorescu and his staff, [22] while the other three monitors - organised as the 2nd Monitor Division - safely evacuated the 9th Romanian Infantry Division. During the following year, the monitors joined the army artillery in holding the line against the Germans in Moldavia throughout the summer and autumn of 1917. In early 1918, the monitors were primarily engaged in sweeping mines from channels, rivers and ports. [23]
During the Balkan Wars of 1912–1913, Romania was the only country in the region to have developed its own aircraft. Bulgaria, Serbia and even the Ottoman Empire lacked native aircraft at the time, but Romania had two machines designed by Aurel Vlaicu – A Vlaicu I and A Vlaicu II – in service with its army. Vlaicu's design had a chain-driven propeller at either end of the wing, the rudder at the front of the aircraft, a triangular tail and a 50 hp Gnome et Rhône engine. At an Austro-Hungarian aircraft contest in the summer of 1912, Vlaicu's "strange-looking monoplane", a "refreshing oddity", took the first prizes for landing in the smallest circle and for accurate "bomb dropping". Vlaicu's aircraft was nicknamed "La Folle Mouche" ("The Crazy Fly"). Although the model was subsequently purchased by the Romanian Army, Vlaicu was killed in a crash during September 1913, which also destroyed his second aircraft. [24] Before Romania's entry into World War I, a Romanian factory started manufacturing Farman aircraft under licence. [25] Six Farmans were ordered and served in the Romanian Air Corps. [26] On the eve of its entry into the war in 1916, the Romanian Air Corps had 24 aircraft and another 20 from the flight schools. [27] [2] During the war, a number of 242-292 aircraft and 545 engines were assembled at RGA. [28] [29] During late 1917, limited assembly of Nieuport 17 fighters also took place at the Romanian port town of Sulina. The aircraft assembled there arrived in crates at Chilia. On 7 October, two assembled fighters were already in service at Sulina, and by the end of the year, four more operational and two non-operational aircraft were added. It is not known for certain if the Sulina air unit was involved in any combat. [30]
In 1915, an armored car was designed at the CFR workshops in Bucharest. It used the chassis of a truck that was being repaired at the workshops. The armored car could mount a single machine gun. [31]
During the war, when the workshops were located at Iași, another armored car was built. This armored car was larger and it was equipped with a machine gun, as well as with a Burileanu anti-aircraft gun. No photos exist of this armored car. [31]
During the Hungarian-Romanian War of 1919, the Romanian Army used an armored car of native design and construction. The car used the chassis of a commercial truck, possibly from one of the Renault trucks received in 1916. Presumably, the design and construction of this machine took place at the end of 1918 and were finished in 1919. [32]
There is no description of its construction. Presumably, a wooden (or steel) frame was installed on a 4x2 truck chassis, on which sheets of steel armor were attached with rivets and bolts. The thickness of the armor could have been from 6 to 8 mm. A hexagonal turret in which a machine gun could be mounted was installed on the roof of the hull. It is known for sure that this armored car participated in the entry of the Romanian troops into Budapest in August 1919. [32]
The Romanian-born inventor Henri Coandă designed several models of aircraft for the British Bristol Aeroplane Company. In January 1912, he was formally appointed Bristol's leading technician. His first design was the Bristol-Coandă monoplane. This aircraft was tested for the first time at Larkhill in March 1912. It was manufactured in both tandem and two-seater modes. Powered by an 80 hp Gnome et Rhône engine, the aircraft had a four-wheeled undercarriage and incorporated wing-warping for lateral control. This Romanian design gained Bristol the third prize during a flying competition. Italy ordered up to 14, while Romania itself ordered 10. In October 1914, Coandă left Bristol and returned to Romania. [33] Despite a subsequent ban on monoplanes, Coandă's design was still much talked about, being rated as one of the leading machines of the day. Still, it was the influence of Coandă's father - General Constantin Coandă - that was decisive in the adoption of the model by Romania. [34] The Bristol T.B.8 biplane was developed from the Coandă monoplane. A total of 53 were produced, including conversions from Coandă monoplanes. [35] Coandă invented a new bomb-dropping device for these biplanes, containing twelve bombs which could be released by a hand lever in the observer's seat. The Coandă biplanes, made using the same fuselage as the Coandă monoplanes, were much better than the latter, but still had a glaring flaw: they were tail-heavy. Coandă obstinately refused to address this issue, being adamant that his calculations were correct. The planes were, in fact, "a bit tail heavy". [36] The "Bristol-Coandă Bomb Rack One", as it was called, was put to use solely on the Bristol-Coandă T.B.8 biplane. [37] Throughout the summer of 1913, the structurally suspect Coandă monoplane was modified and converted to this tractor-biplane configuration, known thereafter as T.B.8. The design proved moderately successful, a manufacturing licence for it being subsequently acquired by the French firm Bréguet. [38] The T.B.8 was used as a bomber only once, on 25 November 1914, when one made a bombing attack on German artillery batteries at Middelkerke, Belgium. [39] Romania itself acquired 7 Bristol-Coandă monoplanes and 10 Bristol-Coandă T.B.8 biplanes. [40] Given that, on the eve of its entry into the war in 1916, the Romanian Air Force had 44 aircraft, [27] [41] this means that a significant part of Romania's air power was Romanian-designed: the 17 aforementioned Coandă aircraft plus the remaining airplanes designed and built by Aurel Vlaicu.
The Romanian engineer George Constantinescu, working with Vickers in the United Kingdom during the war, invented what would become the main synchronizing device for the Royal Air Force. Constantinescu's men constructed the synchronizing gear within 9 days. It was such a simple but so completely effective device, that hundreds of thousands were made with no modifications needed. [42] Although initially designed to fire only one machine gun, the Constantinescu gear was soon adapted to operate two, mounted parallel to each other. The Romanian design made the Vickers machine gun a superb aircraft weapon, given that it was a reliable synchronizing gear. A brilliant achievement of the Romanian engineer. [43] The Constantinescu gear began being used starting with early 1917, when production aircraft started being delivered armed with a forward-firing Vickers gun synchronized with the Constantinescu gear. [44] Among the aircraft fitted with the Constantinescu synchronized forward-firing equipment was the Sopwith Pup. [45] In August 1917, American representatives sent to Europe by the War Department acquired two Vickers aircraft machine guns equipped with the Constantinescu synchronizing gears. [46]
Parnall was a British aircraft manufacturer that evolved from a wood-working company before the First World War to a significant designer of military and civil aircraft into the 1940s. It was based in the west of England and was originally known as George Parnall & Co. Ltd.
A synchronization gear was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target.
Henri Marie Coandă was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft, the Coandă-1910, which never flew. He invented a great number of devices, designed a "flying saucer" and discovered the Coandă effect of fluid dynamics.
This is a list of aviation-related events from 1910:
World War I was the first major conflict involving the large-scale use of aircraft. Tethered observation balloons had already been employed in several wars, and would be used extensively for artillery spotting. Germany employed Zeppelins for reconnaissance over the North Sea and Baltic and also for strategic bombing raids over Britain and the Eastern Front.
In aviation, the term tractor configuration refers to an aircraft constructed in the standard configuration with its engine mounted with the propeller in front of it so that the aircraft is "pulled" through the air. Oppositely, the pusher configuration places the airscrew behind and propels the aircraft forward. Through common usage, the word "propeller" has come to mean any airscrew, whether it actually propels or pulls the plane.
A gun turret is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation.
Romania has a rich tradition in aviation. At the beginning of the 20th century, pioneers such as Henri Coandă, Aurel Vlaicu, Traian Vuia and George Valentin Bibescu made important contributions to early aviation history, building revolutionary airplanes and contributing to the international scene.
The Bristol Scout was a single-seat rotary-engined biplane originally designed as a racing aircraft. Like similar fast, light aircraft of the period it was used by the RNAS and the RFC as a "scout", or fast reconnaissance type. It was one of the first single-seaters to be used as a fighter aircraft, although it was not possible to fit it with an effective forward-firing armament until the first British-designed gun synchronizers became available later in 1916, by which time the Scout was obsolescent. Single-seat fighters continued to be called "scouts" in British usage into the early 1920s.
The Bristol M.1 Monoplane Scout was a British monoplane fighter of the First World War. It holds the distinction of being the only British monoplane fighter to reach production during the conflict.
The Ordnance QF 4.5-inch howitzer was the standard British Empire field howitzer of the First World War era. It replaced the BL 5-inch howitzer and equipped some 25% of the field artillery. It entered service in 1910 and remained in service through the interwar period and was last used in the field by British forces in early 1942. It was generally horse drawn until mechanisation in the 1930s.
The Bristol T.B.8, or Bristol-Coanda T.B.8 was an early British biplane built by the Bristol Aeroplane Company and designed by the Romanian Henri Coandă. Fifty four Bristol T.B.8s were built, being mainly used as a trainer. A small number of Bristol T.B.8s were briefly used as bombers at the start of the World War I by the Royal Naval Air Service.
The Bristol Coanda Monoplanes were a series of monoplane trainers designed by the Romanian designer Henri Coandă for the British company British and Colonial Aeroplane Company.
Before 1989, Romania was among the top ten arms exporters in the world, however its arms industry declined considerably during the 1990s. Exports fell from roughly $1 billion before 1989 to about $43 million in 2006, and the number of employees also fell from 220,000 in 1990 to 20,000 in 2009. Sales to the Romanian Armed Forces have plunged after Romania's accession to NATO in 2004, as factories continue to produce Warsaw Pact-caliber weapons and ammunition, which are incompatible with their Western counterparts.
The Bristol B.R.7 was a Romanian-designed single-engine two-seat biplane built by Bristol to a Spanish government order in 1913. It failed to meet its specifications and the order was cancelled.
Cecil Howard Pixton was a British aeronautical engineer, test pilot and air racing pilot who was most famous for winning the 1914 Schneider Trophy seaplane race.
The Bristol P.B.8, or Bristol-Coanda P.B.8', was an early British-built, Romanian-designed two-seat biplane trainer made by the Bristol Aeroplane Company in 1914. Only one was completed, which was never flown.
The Romanian Air Corps or Aviation Corps (RAC) was the air arm of the Romanian army until the formation of the Romanian Air Force. It was established on 1 April 1913 as the Military Aeronautics Service and subordinated to the Engineer Inspectorate, being organized in two branches – the aviation and the balloon branch. On 23 August 1915, the RAC was formed as an independent military arm and operated until 1 January 1924 when it became an equal to the Army and Navy, being redesignated as the Royal Romanian Air Force.
NMS Mihail Kogălniceanu was a monitor of the Romanian Navy. She saw service in both world wars, being the most successful vessel in her class of four ships. Like her three sisters, she was initially built as a river monitor, but in early 1918, she was converted to a sea-going monitor. During the Second Balkan War, she supported the Romanian crossing of the Danube into Bulgaria. During World War I, she carried out numerous bombardments against the Central Powers forces advancing along the shore of the Danube and carried out the last action of the Romanian Navy before the 11 November 1918 armistice. She later fought successfully against Bolshevik naval forces during the early months of the Russian Civil War, helping secure the Budjak region. During the interwar period, she contributed to the suppression of the Tatarbunary Uprising and was rearmed with longer main guns towards the end of the 1930s. During World War II, she fought several engagements against the Soviet Navy in the first month of the Eastern Front, but was ultimately sunk by Soviet aircraft shortly after Romania ceased hostilities against the Soviet Union, on 24 August 1944.
The Army Arsenal of Bucharest was the main arsenal of the Romanian Army, established in 1861 with the task of manufacturing, maintaining, and storing weapons, as well as limbers and caissons for the artillery. The old flags, uniforms, and weapons of the Romanian Army were also stored at the Arsenal until 1919.
