Number built	1

The Morane-Saulnier AF, also known as the Morane-Saulnier Type AF and the MoS 28 was a French fighter prototype of the 1910s.

Development

Although the fuselage was based on the Morane-Saulnier Type AC, this aircraft was different from it. The first single-seat biplane fighter developed by Morane-Saulnier, the AF was delivered to the Aviation Militaire in late 1917 for testing.

Operational history

First flying on 23 June of that year, the AF showed excellent handling and good performance. However, it was deemed inferior to the SPAD S.XIII which was already in quantity production. Morane-Saulnier adapted the design to a floatplane, as described below.

Variants

• Morane-Saulnier AFH
  • In November 1917 a floatplane version of the AF was readied for testing. Equipped with a single central pontoon-like float, some flight testing was carried out but the aircraft was never adopted.
