A blue specter over the broad waves of the Pacific Ocean, the heavily armed Consolidated Privateer lived up to its name in World War II.
The Navy began the war in 1941 with its primary long-range patrol bomber being the PBY Catalina flying boat, which provided yeoman service throughout the conflict, but the service also immediately found the need for a large land-based patrol bomber. A variant of the Consolidated B-24 Liberator, dubbed the PB4Y-1 Liberator in Navy service, was soon flying, with over 900 produced.
Nonetheless, the Navy still wanted something more navalized than the Liberator, and in 1943, Consolidated cooked up a new plane based on the Liberator but optimized for low-altitude patrol missions. This led to the PB4Y-2 Privateer, which was approximately 7 feet longer, had more powerful engines that added another 600 horsepower to the aircraft's powerplant, and featured a large (30-foot-high) single tail rather than the B-24's 17-foot-high twin-tailed format.
Oh yeah, and it had much better guns.

While primarily built to haul around up to 8,000 pounds of bombs and drop them on things of interest, the PB4Y-2 was a beast, clad in 3,343 pounds of armor plate over vital areas, augmented by bullet (resistant) glass. It also carried a full dozen Browning AN/M2 .50-caliber heavy machine guns, more guns than the 10 on the B-24 Liberator and the B-29 Superfortress, and almost as many as the famed B-17G Flying Fortress (13).

The standard loadout for the guns was 4,800 rounds of ammo in a mix of tracer, ball, and armor-piercing, although more rounds could be carried. The 11-man crew included six dedicated gunners, with the other five members (pilot, co-pilot, navigator, bombardier, and radio operator) operating the plane.
For sighting, the Privateer had Mk. 9 illuminated sights in the nose, tail, and waist, while the gunners in the top deck turrets used a special Mk. 18 sight.
The two .50s in the nose turret were stoked with 1,200 rounds. The distinctive ERCO 250SH turret was designed specifically for naval use, and it had a superb field of fire, able to elevate 85 degrees high and depress 70 degrees low while rotating 80 degrees left and right.

The two guns in each of the two waist turret positions each had 1,000 rounds. Rather than the flexible open single mounts as seen in the B-24, these ERCO 250TH teardrop-shaped blister turrets used a hydraulic pump powered by an electric motor. They could train 79 degrees aft and 56 degrees forward and be elevated to 60 degrees and depressed 95 degrees down. (Photos: Chris Eger/Guns.com)
Two .50 cals were carried in the top forward deck turret and two in the top rear deck turret, each with 800 rounds. The only other WWII American bomber to carry two dorsal turrets was the B-29. (Photo: Chris Eger/Guns.com)

This armament made the Privateer deadly when it came to anti-shipping roles, with many squadrons racking up long scorecards of tonnage sent to the bottom. Besides its bombs, the aircraft's guns came in extremely handy in such strafing runs.

Speaking of strafing runs, the Privateer also attacked targets on land as needed, such as this image of one stitching up a Japanese train in Korea.

The gun armament also turned the Privateer, often flying lonely 2,000-mile missions over empty ocean, into the worst thing that a Japanese patrol plane could encounter.

The Navy kept extremely detailed records of each air-to-air shootdown of enemy aircraft by its patrol planes. This included seven by PB2Y Coronados, 17 by PBM Mariners, 18 by PBY Catalinas, 21 by PV Ventura/Harpoons, and a seriously impressive 323 by PB4Ys.
Two PB4Y squadrons, VPB-117 and VPB-104, splashed more than 50 planes each, while three others broke 20. Impressively, 39 of VPB-104's shootdowns were logged in just a six-month period when flying out of Guadalcanal and Munda field, New Guinea, in late 1943/early 1944.
Eight PB4Y crews in the Pacific were "aces" in a sense, as they shot down more than five aircraft each. One gunner, ARM2 Paul A. Ganshir, a top turret man with VD-3, downed five by himself. A bow turret gunner with VPB-117, S1c Richard H. Thomas, had five Japanese planes to his credit.
Tellingly, while the B-24 and B-17 never made it to fight over Korea in the 1950s, the Navy sent seven Privateer squadrons to that war, with the big patrol bombers shrugging off attacks from Chinese MiG-15s on at least two different occasions while on patrol off China.
Consolidated built 739 PB4Y-2 Privateers during the war. BuNo 59819, one of only about a half dozen such aircraft remaining in existence, is at Pima after finishing its Navy career in 1965. It had a second career as an aerial tanker based in Arizona, fighting forest fires for another 25 years until it retired a second time in 1990. (Photo: Chris Eger/Guns.com)
