103 Squadron - WW1

While flying the DH9 103 Squadron used 2 types of bomb during WW1/1918 with some success.

The main targets for these were German airfields, troop concentrations and communications on the Western Front

High Explosive 112 lb Mk 1/2 - Heavy Cast Steel - 35 or 40 lb Amatol TNT – Usually 2 were carried.

High Explosive 230 lb - Light/Mild Steel - 110 or 140 lb Amatol TNT – Used in early stages.

103 Squadron - Interwar

From 1936 to 1938 103 Squadron operated the Hawker Hind bi plane bomber.

This aircraft could carry up to 4 Medium Capacity 100 lb High Explosive bombs under the lower wing.

These however were never used in anger as the Hinds were replaced by the Fairey Battle in 1938.

During the Battle of France 103 Squadron used standard Medium Capacity 250 lb General Purpose bombs fitted in four wing cells giving a load of 1000 lb. On return from France there is also mention of the use 40 lb General Purpose Fragmentation bombs and unspecified small Incendiary bombs. 103 Squadron used the former invasion barges in the French Channel ports

Vickers Wellington – 103 Squadron.

Vickers Wellington bombing up

Bombing up a Wellington prior to an op. The load suggests a naval target. I think the larger bomb on the left is a 1000 lb SAP. The others are 250 lb GP bombs. There is no record that the 103 Wellingtons carried the 1000 lb SAP - only 500 lb SAP

With the conversion of 103 Squadron to the Vickers Wellington medium twin engined bomber in late 1940 the weight of bombs carried was significantly increased. Also the weapons used became more varied and included sea mines which became available in early 1942.

These weapons used by 103 Squadron on this type are listed below :-

250 lb General Purpose and Semi Armour Piercing

The Halifax four engined bomber was able to carry a significantly heavier bomb load than the Wellington. 103 Squadron operated the type from the beginning of August 1942 to the end of October 1942 when they converted to Lancasters. The payload carried by 103 Squadron during this period was restricted to 2 types as set out below.

1000 lb General Purpose

4 lb Incendiaries in small bomb containers.


Avro Lancaster Bombing Up

Avro Lancasters – 103 Squadron and 576 Squadron.

The Lancaster equipped 103 Squadron from November 1942 to the end of WW2 and 576 Squadron from its formation in December 1943 to the end of WW2. It proved an excellent machine with good handling characteristics, performance and reliability and also had the added advantage of a long unobstructed bomb bay enabling it to carry a variety of bomb loads including all the heaviest weapons used by the RAF during WW2

103 Squadron – Post war

103 Squadron was reformed on the 30 November 1954 and was part of the 2nd Tactical Air Force at RAF Gutersloh. At this time the unit flew the excellent English Electric Canberra B 2 jet bomber. This was the final bomber type operated by the Squadron which was disbanded again 1 August 1956. The Canberra carried a bomb load of 6000 lb. As far as I know during its  short career with 103 Squadron the Canberra carried 6 General Purpose Medium Capacity 1000 lb bombs stowed in the internal bomb bay
