The B-27 was designed as a 4-engine version of the B-26 Marauder, with additional defensive armament in the form of two Sperry A-17A ball turrets in the nose and tail positions, as well as a Martin 250CE top turret and a Martin designed remote controlled belly turret. First used against U-Boats during the Battle of the Atlantic, where it earned the nickname of “Atlantic Marauder”, the aircraft was used in both the PTO and ETO, replacing the B-24 Liberator. Units in the PTO referred to it as the “Pacific Marauder” instead.

Due to the large wing area, the plane had a much lower wing loading of only 36.7 lb/ft², compared to the 46.4 lb/ft² of late Marauders and the 56 lb/ft² of the early models on which it was based. Such wing loading was also lower than the B-17’s (38 lb/ft²) and the B-24’s (52.5 lb/ft²). This, combined with the aircraft’s smaller size and more powerful engines, made it much faster and more maneuverable than either aircraft, while also making the B-27 very resistant to battle damage, and giving it a shorter takeoff distance when compared to the B-26.


Something I’ve been working on for the past few weeks. War Thunder’s having an art contest where you have to design a vehicle. I might have gone a little overboard, since I not only spent a lot of time making sure none of the drawings disagreed too much and doing research into how much my changes to the original B-26 design would affect performance. Took up 4 sheets of paper overall and the front view alone took around 3 hours. Interior views (left to right): Outer engine nacelles (engines 1 & 4, bomb bays), inner engine nacelles (engines 2 & 3, landing gear well), fuselage and main landing gear (shown from behind).


The Coupés from the midsize series (from front to back) are the Coupés from the W124 series (1987 to 1996), W123 series (1976 to 1985) and W114 series (1968 to 1976)

Personal note: growing up in New Zealand some friends of my parents had a W114 250CE which, as a child, I thought was very special indeed. They had a bad accident in it but a tribute to Mercedes safety engineering, they walked away with a few bruises though the car was damaged beyond repair. They replaced it with a Series 3 Jaguar XJ6
