It was the Washington National Airport in 1941.
The airport opened, obviously, just before the United States' entry into the Second World War, it's 1941 opening partially explained by a prohibition in airport funding that was lifted in 1938.
Washington National in 1944.
It was built on grounds near Arlington that had been part of a large plantation, but its location very much constrains it size, so it remains a shockingly small airport in spite of its signficance.
It was renamed for President Ronald Reagan in 1998.
I've personally never flown into it, having landed at the nearby Baltimore airport once.
