The Loring R-III or R-3 was a 1920s Spanish two-seat sesquiplane reconnaissance and light attack aircraft designed by engineer Eduardo Barrón and built by Dr. Jorge Loring's company — Talleres Loring.




Operational history


In the mid 1920s, during General Primo de Rivera's dictatorship the R-III entered a contest along with the Potez 25 for the modernization of the Spanish Military Air Arm. Both planes had similar characteristics, but the Military Directory favoured the Loring R-III in order to promote local industries.
The Aeronáutica Militar placed an order of 110 units, which put the Loring company at the head of the Spanish aeronautical industry of the time.
In October and November 1926 three variants of the R-3 were exhibited at the Loring section of the National Aeronautics Exhibition held in Madrid's Palacio de Cristal: The R-3, the C-1 fighter and the T-1 light trainer. Neither the fighter nor the trainer variants, however, went into production.
Some R-3s remained in service well after the proclamation of the Spanish Republic until the outbreak of the Spanish Civil War. It is not clear, however, whether they saw active service in the civil war.
