Might make more sense from the front page, but the picture is unrelated to the T2V-1/T-1A they're talking about.

T-1
The Lockheed Seastar was a development of the T-33 and was unofficially designated as T-33B. The development was company funded and the first flight took place on 15 December 1953 with the prototype registered N125D. The US Navy placed orders for 150 T2V-1s from May 1954 and with serials 142261/142268, 142397/142399, 142533/142541, 144117/144216 and 144735/144764. Production of batches with serials 144765/144824 and 146058/146237 was cancelled. On 18 September 1962 those aircraft remaining in service were redesignated as T-1A.
In 1990 the designation T-1A was assigned to the Tanker Transport Trainer Aircraft, Beechcraft Jayhawk. The aircraft was based on the Beechjet 400, itself a derivative of the Mitsubishi Diamond 2. There is a requirement for 211 aircraft and production was undertaken by McDonnell Douglas after the dissolution of Beechcraft. Serials are 89-284, 90-398/413, 91-075/102, 92-330/363, 93-621/656, 94-114/148, 94-621/656, 95-004/071. The first flight took place on 5 July 1991. A number of aircraft were used as CT-1B transports.
