Early in 1945 a desire to standardize the fighter-bombers in Ninth Air Force, the group transitioned into Republic P-47 Thunderbolts.
Pilots flew Lightings on combat missions while training at the same time with the Thunderbolt.
Using the Thunderbolt the group was again cited in a Belgium Army Order of the Day, earning the Belgian Fourragere.

The 392d received a second Distinguished Unit Citation for action on 19 March 1945.
 The 367th Group's target was the headquarters of Field Marshal Kesselring, the German Commander-ln-Chief, West, at Ziegenburg near Bad Nauheim, Germany.
 Aircraft of the leading 394th Fighter Squadron would attack at low level to achieve surprise, carrying a 1,000-pound bomb under each wing.
The P-47s of the 392d would be similarly armed, but would dive bomb from a higher altitude.
 The bombs were equipped with time-delay fuses intended to crack the concrete roofs of the bunker.
The 393d Fighter Squadron carried napalm intended to seep into the bunkers and burn what remained.
The attack was scheduled for a time that intelligence reports indicated would find senior staff and commanders at lunch, the only time they would not be in the reinforced tunnels underneath the castle that housed the headquarters.
The target was located in mountainous terrain well defended by antiaircraft artillery.
 Moreover, to avoid alerting the Germans to the pending attack, photographic reconnaissance aircraft had avoided the area, so detailed target photography was not available.
 The day of the attack the castle was concealed by ground haze which caused the 394th Fighter Squadron to stray off course at the last minute, preventing them from executing the attack as planned and reducing the element of surprise.
Although senior German officers reached the underground bunkers and survived the attack, the group reduced the military complex to ruins, disrupting communications and the flow of intelligence at a critical time.

The squadron struck tanks, trucks, flak positions, and other objectives in support of the assault across the Rhine late in March and the final allied operations in Germany.
It was commended by the commanding generals of XII Corps and the 11th Armored Division for the close air support the unit provided for their commands.
On 10 April the squadron moved to Eschborn Airfield on the northwest side of Frankfurt, Germany.
The 392d flew its last combat mission, a defensive patrol, one year after entering combat on 8 May. During its combat tour, the squadron was credited with 39.5 air-to-air victories over enemy aircraft, the most of any of the squadrons in the group.
