Heinkel He 111 — Medium Bomber
Open in interactive gallery →

The Heinkel He 111 was the German twin-engine medium bomber that served as the Luftwaffe's principal bomber from the Spanish Civil War through 1944. The Günter brothers designed the He 111 in 1934 as a civilian fast-airliner derivative of the He 70 Blitz, with secret military-bomber dual-use intent. The prototype first flew on 24 February 1935. About 7,300 He 111s were built between 1936 and 1944 at Heinkel Oranienburg + Heinkel Rostock + multiple licensed plants. The aircraft saw extensive combat in the Spanish Civil War, the Battle of Britain, the Blitz, the Eastern Front, and North Africa.

The He 111H (the most-numerous variant) used two Junkers Jumo 211 V-12 engines (1,200-1,340 hp each). Maximum speed 440 km/h, range 2,300 km, service ceiling 8,500 m. Bomb load 2,000 kg internal — sufficient for field-bomber missions but inadequate for true long-range bombing. Defensive armament: 6-7 machine guns (some He 111H-22 variants carried MG 131 13 mm guns). Crew: 5-6 (pilot + navigator/bombardier + radio operator + 2-3 gunners). The aircraft's distinctive fully-glazed nose section housed the navigator-bombardier position.

He 111 service was extensive across every major WWII Luftwaffe combat theatre. The 1937-1938 Spanish Civil War Condor Legion deployment proved the aircraft's combat effectiveness against Republican forces. The 1940 Battle of Britain saw heavy He 111 use against British cities — with substantial losses to RAF Spitfire + Hurricane fighters (over 200 He 111s lost in summer 1940 alone). Eastern Front operations 1941-1945 dominated the He 111's combat service, including air-bridge supply attempts to encircled Stalingrad in winter 1942-1943. Spanish licence-built CASA 2.111s served Spanish Air Force from 1945 to 1973 (some carrying Rolls-Royce Merlin engines after Junkers Jumo production ended). About 5 He 111 airframes survive in 2026 at German, British, and Spanish museums.

For Kids — a shorter, friendlier version

The Heinkel He 111 was one of Germany's main bombers in World War II. You can recognize it by its glassed-in nose — the bombardier sat right in the front, looking straight ahead and down through a huge curved window made of dozens of small glass panels. The shape looked like a giant glass dragonfly head.

The He 111 first flew in 1935 — disguised as a commercial mailplane to hide Germany's bomber rebuilding. It entered combat in 1937 during the Spanish Civil War. By WWII, the He 111 was Germany's main bomber along with the smaller Junkers Ju 88 and Dornier Do 17.

The He 111 has two engines on the wings and a crew of five. It's about 54 feet long — longer than a school bus. Top speed about 270 mph. Bomb load up to 5,500 pounds. The crew had three machine-gun positions — one on top, one on the bottom, and one in the nose alongside the bombardier.

About 6,500 He 111s were built between 1935 and 1944. They bombed Britain during the Battle of Britain (summer 1940) and many other Allied countries. The He 111 was too slow to escape modern Spitfires and Hurricanes, so bomber losses were severe.

After WWII, Spain built about 200 He 111s under licence (called the CASA 2.111) which kept flying until 1973. About 5 original He 111s still exist; one CASA 2.111 still flies in California at airshows.

Kids’ Questions

Why was the nose all glass?

Before electronic bomb sights and radar, the bombardier had to look directly at the target to aim. The He 111's glass nose gave the bombardier the best possible view — looking straight ahead and down through a giant curved window made of dozens of small glass panes. The bombardier could see the target, aim through a bombsight, and call out "bombs away" to the pilot at the right moment. The downside was that glass is fragile — the He 111's nose was an easy target for fighter machine guns. Many bombardiers were lost during attacks.

Was the He 111 a good bomber?

Yes for 1937, no for 1940. When the He 111 first flew in 1935, it was one of the best medium bombers in the world — fast (270 mph was very quick then), reliable, and well-built. But by the Battle of Britain in 1940, faster British fighters like the Spitfire (370 mph) and Hurricane (340 mph) could easily catch up to He 111s. Without enough fighter escort, He 111s were lost in large numbers. Germany kept using them anyway because they had no better bomber ready. By 1944 the He 111 was hopelessly outdated, but Germany was running out of options.

Frequently Asked Questions

Was the He 111 a good bomber?

Mixed. The He 111 was effective against weak air defences (Spanish Civil War, early Poland / France campaigns) but suffered heavy losses against modern fighter defences (Battle of Britain — over 200 lost in summer 1940). The aircraft's 2,000 kg bomb load was inadequate for true long-range bombing (compared with 6,000+ kg for Allied Lancasters / B-17s). The Luftwaffe's doctrine of medium-bomber-only deployment limited Allied long-range bombing damage; the He 111 was the principal example of this limitation.

Why does the He 111 have a fully-glazed nose?

To give the navigator/bombardier maximum visual angle for visual bomb-aiming. Standard Luftwaffe bombing doctrine used optical bombsights operated by the navigator in the nose section; the fully-glazed nose gave him unobstructed forward-down visibility. The same design choice was used on the Junkers Ju 88 and Dornier Do 17. By the mid-war years, Allied bombers were transitioning to nose-radar guidance which made fully-glazed noses unnecessary; the German doctrine retained visual bombsights longer.

Did Spain operate He 111s into the 1970s?

Yes. Spanish CASA company licence-built ~236 He 111s as the CASA 2.111 between 1945 and 1956. Spanish Air Force operated these in front-line bomber, transport, and trainer roles through 1973. Late-production CASA 2.111s were re-engined with British Rolls-Royce Merlin engines (replacing the unavailable Junkers Jumo 211). The CASA 2.111 was the last He 111 variant in active military service worldwide.

How many He 111s were built?

About 7,300 airframes 1936-1944 at Heinkel Oranienburg + Rostock + multiple licensed plants (Junkers, ATG, NDW, others). Plus ~236 Spanish CASA 2.111s 1945-1956. Combined family production ~7,536 — making the He 111 one of the most-produced bombers in history.
