The P-38 would have its weapons centrally
mounted in the nose w/4x50cal.machine guns w/500rpg and 1x20mmcannon w/150rounds.
As a fighter-bomber the P-38 could also carry
up to two tons of bombs.

One Hundred and Fifty, or Sixty Rounds, that is the question? Some sources say the
20mm cannon drum magazine held 150rounds, other sources say the drum magazine held 60rounds.
The bendix Mk II, 20mm cannon used by the US Navy looked like the same type of drum magazine used on the P-38, just wanted to clear this up.

XP-38 mockup mounted 2x50cal. machine guns
w/200rpg and 2x30cal. machine guns w/500rpg
plus 1x23mm cannon w/15rounds.
Experiments with a 1x37mm cannon w/15 rounds was tested, but never put into production aircraft.
In March 1941 the P-38 Lightning was set at
4x50.cal machine guns w/500rpg and 1x20mm
cannon w/150rounds.
Photographs of the P-38 Glacier Girl show a
60 round drum magazine this would give about
six or seven seconds firing time for the
20mm cannon.
The 60 round drum magazine was used briefly before the 150 round magazine and feed system was installed. I would think the 60
round drum magazine on the P-38 was very limited in firing time, it probably wasn't used long operationally.
Did You Know...
In 1934 the US Government's sale of the
Fifty Caliber Browning M-2 Machine gun to
Japan, the Japanese scaled up this design to
20mm model HO5.
Six years later, the US bought the rights to
manufacture the Hispano-Suzia 20mm cannon.

PICKUP THAT BRASS!
Where did all that brass go? when the pilot
fired his guns, the empty shells (brass to
any GI) were expended with links from four chutes in the P-38s nose.
The 20mm cannon shells were bigger, and if ejected would be to close to the propellers
and could cause damage to the fuselage or engines, they were emptyed into a brass catcher and later removed by the ground crew

BEFORE L.A. BECAME A GREAT BIG FREEWAY:
Photograph taken over 1940s Los Angeles,Ca.
before it became a great big freeway.
During World War II Los Angeles would become
a "Boom Town" the area grew faster then any other city in the United States.
GI's who were stationed or processed through on their way to oversea duty, would return settled down and built post-war civilian lives.
People who traveled to California to work would do the same after WWII, Cities like
Costa Mesa, Irvine didn't exist before the war and San Bernardino was in the "Sticks"
thats in the country.
I remember riding my bike down a wide dirt road, in each direction that was being built and would later become a section of the Santa Monica Freeway.
Between July 1941 to August 1945 Lockheed
built 19,000 aircraft, and by 1945 about
23 P-38s left the assembly lines every day
thats about one every hour!

The Lockheed P-38 made its first flight in
September, 1940. When the design for the
P-38 was put down on paper in 1936, with speeds toward 400mph, the Boeing P26 was
the USAAC's first-line fighter.
The "peashooter" as it was nicknamed was an radial engine, open cockpit, wire braced monoplane with fixed landing gear, with a
maximum speed of 234mph, and armed with two
.30 caliber machine guns.
