High Quality Content by WIKIPEDIA articles! The Levasseur PL.15 was a torpedo bomber seaplane developed in France in the early 1930s. It was a follow-on design to Levasseur`s PL.14 that had, in turn, been developed from the carrier-based PL.7. While the PL.14 retained the PL.7`s boat-like fuselage (developed as a safety feature for carrier-based aircraft ditching), the PL.15 was a purpose-built seaplane with an all-new, slender fuselage.
