First conceived by Messerschmitt as a carrier-borne fighter, the Me 155 morphed into a high-speed attack plane and later a high-altitude interceptor known as the Blohm & Voss BV 155.

In order to expedite production as well as ease manufacturing for an already overloaded wartime staff, the new carrier fighter was to utilize as many components of the existing Bf 109 as possible. In late Dec. 1942, the design of the Me 155 was complete. The fuselage would consist mainly of a standard Bf 109G along with tail surfaces, but coupled with an entirely new wing with a 36 ft 3.5 in wingspan.

The main landing gear, with a more carrier-friendly widened stance, would retract inward into wing wells, while the wings had provisions for folding enhancing aircraft storage. Arresting gear as well as catapult spools was also incorporated. Power would come from a Daimler Benz 605A-1 producing 1,475 horsepower at takeoff, and the aircraft had an estimated top speed of 403 mph.

The final design, designated the Me 155B-1 and known to Messerschmitt as P.1091, included a vertical tail from another Messerschmitt design, the Me 209, with the horizontal tail retained from the Bf 109G along with the landing gear. Being overtaxed with design work, the project was sent to a design office in Paris staffed with French aircraft designers, who made little progress. In August 1943, the German Air Ministry (Reichsluffahrtministerium; RLM) determined Messerschmitt was over burdened with previous commitments, production, and development programs. Messerschmitt was instructed to turn the Me 155B program, including all drawings and calculations, over to the Blohm & Voss company.

CONSTRUCTION:

FUSELAGE:
The fuselage is constructed using the “Ladder Jig” method of construction. Maxfliart has a good tutorial on YouTube that explains this method in detail, here’s a link to the tutorial: https://www.youtube.com/watch?v=1yUYY1dqfH8

WING:
The wing is constructed using the Dave Rees’ sliced rib method. Mike Stuart has made a great tutorial on this method which uses a laminated then sliced rib. Here’s a link: https://www.ffscale.co.uk/rees.htm use the wood dimensions as noted on the plans.

EMPENNAGE:
The horizontal stab is made using 3/32” SQ and sheet balsa. Build flat on the plan. When dry I like to add a full rib over the spar and ribs and sand to an airfoil shape.

The vertical stab is made by using a method I picked up from one of the modellers on the old HipPocket Aeronautics site (HPA), called “Walking a strip of balsa around the edge” of wing tips and rudders etc. I measure the width of the widest strip and cut several strips to accommodate the necessary balsa to cover the outline. I us a strip that will hang over the outline and once glued in place and dry trace the outline on the balsa strips and cut and sand to shape. I hope this makes sense. I note 3/32” balsa for a model this large. Once the outline is finished I like to add a vertical spar and use super glue to attach it to the top of the vertical stab. When dry I then add 1/32”x1/8”strips for lribs over the spar attaching to the L.E and T.E.

I hope you enjoy this plan and potential model. There are many Me/Bf-109’s out there but not like this one. Wide gear for landing on a carrier and long wings for reaching the high altitude of those bombers.
