Hi all,

I have some questions about German 7.5cm Flak anti-aircraft guns in the first half of the 30s.

According to the information that I have a 8.8cm Flak 18 was developed by Krupp in Sweden in the early 30s and entered service in 1933.
When the Germans developed the 7.5cm Flak 14? According to the information that I have the 7.5cm Flak 14 is the combination of a 7.5cm FK16n.A. with the carriage of a 7.5cm Krupp Flak L/60. The 7.5cm FK16n.A. was developed in the early 30's so I guess the 7.5cm Flak 14 also would be developed around the same time.
The question is: Why? At this time Germany was already developing the 8.8cm Flak18, which was much better. 8O

It seems that these guns entered in service with Germany, at least in a self-propelled version on Krupp-Daimler KD1 trucks (kanonewagen). See http://www.network54.com/Forum/330333/m ... service%21
Later, 90 7.5cm Flak 14 guns were sold to Spain during the Civil War (towed version).

The same applies to the Krupp 7.5cm Flak L/60 and 7.5cm Rh Flak L/59. When they were developed? Probably during the early 30s. But by this time was already developing the 8.8cm Flak 18, which was much better. I do not understand the reason of these 7.5cm AA guns designs. :?

Many sources also say that the Krupp 7.5cm L60 was sold to Spain and Brazil, but I have not found any evidence of this.

Have anyone any ideas on these questions?

Thanks in advance. Regards Sturm78

Hi all,

Nobody has information about these questions? :(

Well, I have found a photo on Ebay that seems to show that the 7.5cm Flak 14 entered in service with the German army in its towed version also: two 7.5cm Flak 14 on Sd.Ah.201 trailers being towed by Krupp-Daimler KD1 trucks.

Day
One possible reason for the continuing work on 7.5cm flak was the Versaille Treaty clause that restricted Germany to having only 7.5cm and 10.5cm guns. Most of the 8.8cm work was done outside Germany or with outside Headquartered companies, circumventing this clause. Plus not all countries would have welcomed another calibre into their inventory so the 7.5cm might be deemed a better seller. (Hindsight)

Thanks for your answer, Bill13.
Elude the clauses of the Versailles Treaty would be a possibility (I have tried to find the article that forbids 8.8cm AA guns but I have not found, nor tables II and III Annex to Chapter V of Versailles Treaty. Anybody??).

This could explain the projects of Krupp 7.5cm L60 and Rh 7.5cm L59, but for me it does not explain the creation of a cannon as modest as the 7.5cm Flak 14. 8O

I have found reference to a 7,5 cm Flak battery under Luftwaffe control at Kjevik in january 1941. Anyone know if Luftwaffe relied on captured Norwegian 7,5 cm's or the german produced ones?

Hello Tormod

I could not find any information on the reused of the 7.5 Flak (n) by the Luftwaffe ,
but there were used by the Norwegian Forces in 1940 near airfields ( internet )

The other German 7.5 cm Flak guns were mainly used bt the M.Fl.A.

I understand that they were 2 types of 75 mm guns designed and used by Norway in 1940 (http://hem.fyristorg.com/robertm/norge/ ... rence.html): 7.5 cm L/45 M/16 (12 produced) and 7.5 cm L/45 M/32 (from Kongsberg).

The existing guns were most probably used extensively by the Norwegians in April 1940 and the barrels might have been too worn out for the Germans to consider using them in the long run. :idea:

Thanks for the plausible possibilities to the all three of you!
At least one thing is certain, the 7,5 cm flak guns were not put there orginally by the Norwegians, only a few MG's were present at Kjevik when it was taken by the Germans. (by a lone Ju52 low on fuel!)

This was culled from a lengthy Spanish Civil War artillery thread on the Foro de Historia Militar el Gran Capitan a few years ago:

http://www.elgrancapitan.org/foro/viewt ... &sk=t&sd=a

"El Flak 14 fue el producto resultante de adaptar el tubo y cuna del cañon de campaña FK 16 nA al afuste en forma de cruz del cañon antiaereo de 88mm Flak 18.

El Feldkanone FK 16 nA era a su vez resulado de acoplar un tubo de 75mm a la cureña del FK 16 de 7,7 de la 1GM, de ahi lo de Na, neur Art, pieza remozada. El Flak 14 no llego a ser reglamentario en Alemania.

El Flak 14 tenia cierre por cuña horizontal y se empleaba sobre una plataforma de cuatro mastiles de los que los dos de los laterales se plegaban hacia arriba en el transporte, en tanto que el bajo y el delantero se colocaban sobre dos carillos elasticos provistos de neumaticos.

En el verano de 1937, el General Seperrle, Jefe de la Legion Condor, ofrecio al Ejercito la venta de 17 baterias de estas piezas, luego aumentadas a 27. Al final, sobre Octubre, llegaron realmente 22 baterias, es decir, 88 piezas. La totalidad de estas baterias se integraron en el Regimento de Artilleria Antiaerea, organizado a principios de 1938 al mando del Coronel Francisco Iturzeta Gonzalez.

Este Regimiento se componia de 2 Agrupaciones. La primera encuadraba a las baterias afectas a los Cuerpos de Ejercito en Operaciones, la segunda defendia los Aerodromos y ciudades. Participaron estas piezas en las Batallas de Teruel, Ebro, Levante y Cataluña.

Los Flak-14 costaron 160.00 pesetas unidad.Tras la guerra se integraron en varias unidades antiaereas,12 baterias en el Regimiento de AAA n. 75, 3 baterias en el Grupo Independiente de Baleares, otras 3 en el de Marruecos y 4 en el de Canarias.

CARACTERISTICAS:
Calibre: 75mm
Peso en bateria (weight in battery): 3.600 kgs
Peso del Proyectil (weight of projectile): 5.800 gramos
Velocidad inicial (muzzle velocity): 610 m/s
Alcance vertical (vertical range or ceiling): 7.200 metros
Alcance horizontal (horizontal range): 11.700 metros
