Merchant conversions bring seaplanes to the Baltic

Santa Elena entered service in 1915 after further modification and could support a small air group with hangars and hoisting booms. Its later surrender and rapid return to merchant service also show that the conversion produced a useful auxiliary rather than a purpose-built combat carrier. Oswald did not become a seaplane carrier until July 1918, after earlier work as a depot ship and transport, showing how late some conversions arrived. The obscure Adeline Hugo Stinnes 3 may have carried only three seaplanes and probably served more as a harbor support base than a genuinely mobile aviation ship. Together the ships show Germany improvising aviation logistics from available merchant hulls while accepting small air groups and limited mobility.
