The second V11 prototype, but with 1800hp P&W R-2800 Double Wasp and three-blade prop, NX/NR/NC14980 c/n 29, first flew on 9 October 1935 as a demonstrator for the South America market.

Vultee V-11A NR14980
 
The second V11 prototype, built first as a V-11A, it was later modified as the fixed-gear V-11T for Pratt & Whitney's use in engine testing, first flying on 21 January 1940.

Ultimately refitted with 2000hp R-2800, it was destroyed in a crash on 20 March 1945.
 
The V-11G and -11GB were versions with a 1000hp Wright SGR-1820-G2 Cyclone. The V-11G was a two-seater, and -11GB sat three (pilot, bombardier, gunner) with a retractable ventral gun position. One was built as a company test hack on wheels (NX/NR17327) and seven with a 1200hp P&W R-1830-17 went to the USAAC in 1939 for field testing as YA-19 (38-549 to 38-555).

China ordered 30 two-seat Vultee V-11Gs in 1937-38 and then more Vultee V-12s (a more powerful variant) which they were planning to assemble from kits (25 were finished)
 
Four -11GB went to USSR (NR17328-17329 and 2 unregistered) along with some EDO sets to transform them into -11GBS seaplane and -11GBF floatplane attack bombers. Thirty-one more were built under license in the USSR, but later converted as mail carriers.
 
Forty -11GB went to Turkey redesignated -11GBT, and 26 -11GB to Brazil in 1938-39 as -11GB2, the last of which was modified with EDO floats as 11GB2F for the Brazilian Navy, as also was prototype NX21719 in hopes of civil sales, which didn't occur.

The three-place A-19 attack bomber from the V-11GB was all-metal except for the tail control surfaces. The YA-19 (Model V-11GB) first flew on 27 January 1939 and of the seven, three were converted from V-11G and repowered as XA-19 series.
 
 Vult-A19-01
Vultee YA-19
 
The 1940 XA-19A (Model V-11) featured an enlarged, triangular fin and 1200hp Lycoming O-1230-1 engine. The one was converted from a YA-19 and first flew on 22 May 1940. It later became a XA-19C.

Vultee XA-19A
 
YA-19 38-550 was converted to the XA-19B in 1939, powered by an 1800hp P&W R-2800-1 engine.
 
 Vult-A19-03
Vultee XA-19C 38-555
 
Converted from XA-19A 38-555, the 1939 XA-19C 1939 was powered by a 1200hp P&W R-1830-1/-51.

 

The aircraft had limited combat success with the Chinese, and a Brazilian Vultee V-11 made an attack on a submarine, damaging itself in the process. Later developments would have a rear facing gunner at the back of the cockpit plus a rear-facing ventral gun position protruding from the bottom. Most were later used as high speed liaison and transport aircraft.
