Excellent Radoye, it is the Grumman Columbia XJL.
The Columbia XJL is a large single-engined amphibious aircraft designed by Grumman Aircraft but built by the Columbia Aircraft Corp. It was intended to replace the Grumman J2F Duck but the type did not reach production status.
At the end of World War II, Grumman completed a major re-design of the aircraft for the USN as a Wright R-1820-56 powered monoplane amphibian. The new design was turned over to the Columbia Aircraft Corporation for development and construction so that Grumman could focus on the production of fighter aircraft for the USN.
The aircraft strongly resembles the J2F Duck, except for its monoplane layout, and has been referred to as a "single-winged Duck". It is, however, a completely new design.
The USN ordered three XJL-1 experimental aircraft from Columbia, with the first being used for destructive strength testing on the ground. The remaining two airframes, assigned USN BuAer Nos 31399 and 31400, were delivered to the USNs test establishment at Patuxent River Naval Air Station Maryland for evaluation in 1946.
The two aircraft tested at Patuxent River were found to have repeated structural failures of various components and testing was abandoned on 21 September 1948. The aircraft were deleted from the USN inventory in February 1949. No further orders were placed for production of the JL design.
Your turn Radoye.
