Douglas B-66 Destroyer

Douglas Aircraft · Bomber · USA · Early Jet (1946–1969)

The Douglas B-66 Destroyer was an American twin-engine jet light bomber + reconnaissance aircraft — USAF's principal jet-powered light bomber + ECM platform of the 1950s-1970s. Douglas designed the B-66 in 1952-1954 as a USAF derivative of the U.S. Navy A-3 Skywarrior; first flight 28 June 1954. About 294 B-66s were built between 1954 and 1958 at Douglas Long Beach. The aircraft served USAF 1956-1973 in bomber + reconnaissance + electronic-warfare + weather-reconnaissance roles.

The B-66B used 2 × Allison J71-A-13 turbojet engines (10,200 lbf each). Maximum speed 1,030 km/h, range 2,540 km, service ceiling 12,000 m. Bomb load 6,800 kg internal — sufficient for nuclear strike delivery. Crew: 3 (pilot + navigator/bombardier + gunner). The aircraft was the principal USAF light bomber of the late 1950s + transitioned to specialised ECM + reconnaissance roles in the 1960s.

B-66 service was concentrated in USAF light-bombing + Vietnam War electronic-warfare operations. RB-66 reconnaissance variants flew Cold War long-range photo-reconnaissance missions over Eastern Europe + Vietnam. EB-66 ECM variants flew Vietnam War SEAD (Suppression of Enemy Air Defenses) missions 1965-1973 — jamming North Vietnamese SAM radar + escorting F-4 + F-105 strike formations. About 6 EB-66s were lost in Vietnam combat to MiG-21 + SAM attacks. The aircraft was retired by 1973 in favour of newer ECM platforms (EF-111 Raven + EA-6B Prowler). About 4 B-66 airframes survive in 2026.

For Kids — a shorter, friendlier version

The Douglas B-66 Destroyer was an American jet bomber. It was built for the United States Air Force in the 1950s. The plane had two jet engines and carried a crew of three people.

Douglas first designed the B-66 in 1952. It made its first flight on June 28, 1954. About 294 of these planes were built between 1954 and 1958. That is a lot of aircraft rolling out of one factory!

The B-66 could fly faster than most cars ever dream of going. Its top speed was over 640 miles per hour. It could carry a very heavy load of bombs inside its body. It could also fly very high — nearly as high as 40,000 feet.

Later versions of the B-66 did special jobs. Some took photos during the Cold War. Others jammed enemy radar signals during the Vietnam War. These special planes were called EB-66s. They helped protect other aircraft by confusing enemy defenses.

The B-66 Destroyer served the Air Force from 1956 all the way to 1973. That is nearly 20 years of service! It started as a bomber and finished as an electronic-warfare expert.

Fun Facts

The B-66 Destroyer made its very first flight on June 28, 1954.
About 294 B-66s were built — that is more planes than most schools have students!
The B-66 was faster than a cheetah times 20 — topping over 640 miles per hour.
The plane carried a crew of three: a pilot, a navigator, and a gunner.
Its bomb bay could hold heavier than five average family cars worth of bombs.
The B-66 was based on a Navy plane called the A-3 Skywarrior.
EB-66 versions jammed enemy radar to protect friendly pilots during the Vietnam War.
The B-66 served the Air Force for almost 20 years, from 1956 to 1973.

Kids’ Questions

What did the B-66 Destroyer do?

The B-66 Destroyer was a jet bomber for the Air Force. It could drop bombs and take spy photos. Later versions jammed enemy radar to keep other planes safe.

How many people flew in the B-66?

Three people flew in the B-66. There was a pilot, a navigator who helped aim the bombs, and a gunner. Each person had an important job on the plane.

What is an EB-66?

The EB-66 was a special version of the B-66. It did not drop bombs. Instead it sent out signals to confuse enemy radar during the Vietnam War. This helped protect other aircraft flying nearby.

How fast could the B-66 fly?

The B-66 could fly at over 640 miles per hour. That is faster than most other planes of its time. It could also fly very high up in the sky.

Variants

B-66B (bomber): Standard tactical bomber. About 72 built.
RB-66B / C (reconnaissance): Photo-reconnaissance variants. About 145 built.
EB-66B / E (ECM): Electronic-warfare variants. About 77 conversions + new builds.

Notable Operators

USAF (1956-1973): Sole operator. Light-bombing + reconnaissance + ECM + Vietnam War SEAD.

Frequently Asked Questions

Was the B-66 a Navy aircraft?

Derived from one. Douglas designed the B-66 as a USAF derivative of the U.S. Navy A-3 Skywarrior — sharing wings, engines, + basic fuselage configuration. Significant differences: ground-launch-only operation (no carrier capability), different avionics, modified bomb bay for USAF nuclear weapons + USAF crew layout. The Navy A-3 served carriers as a heavy attack aircraft; the USAF B-66 served land bases as a light tactical bomber. Both designs shared Douglas Long Beach production tooling.
