A comparative evaluation between the F4H-1 and the F-106A took place under the code name Operation Highspeed. The F4H-1 had better overall speed, altitude and range performance than the F-106A. In addition, it could carry heavier loads than the F-106A over longer distances and had a 25 percent greater radar range. Later, the Air Force also looked into the possibility of using the Phantom as a tactical fighter and as a tactical reconnaissance aircraft. The F4H-1 was much more versatile than the Air Force's F-105 Thunderchief, since it could not only carry similar external loads but was also potentially a much better air superiority fighter due to its more favorable wing and power loadings. In the reconnaissance role, the Phantom offered a much better performance than the RF-101A/C, and unlike the Voodoo, could be fitted for night photographic missions.

Since the Phantom had so much going for it, in January of 1962, President Kennedy requested Congressional approval for the procurement of F4H-1 derivatives for the Air Force under the designation F-110. The F-110A was to be the tactical fighter version, with RF-110A being the tactical reconnaissance version. The name Spectre was assigned to the aircraft.

In support of this program, the Defense Department instructed that McDonnell deliver two Navy F4H-1s to the Air Force for evaluation. On January 24, 1962, the two Navy F4H-1s (BuNos 149405 and 149406) were delivered to the Air Force at Langley AFB in Virginia. They were painted in USAF markings with the designation "F-110A" prominently displayed on the nose, but initially retained their Navy BuNos. They were later given Air Force serials 62-12168 and 62-12169 respectively.

The results of the trials were impressive. The Phantom met or exceeded all the Air Force's expectations. In March of 1962, the Defense Department announced that land-based versions of the Phantom were to be the standard tactical fighter and tactical reconnaissance aircraft of the USAF. On March 30, McDonnell received a letter of intent for one F-110A (serial number 62-12199), and on May 29, another letter was received for a pair of YRF-110A reconnaissance aircraft (62-12200 and 62-12201).

In order to formalize the F-110 project, the Air Force issued Specific Operational Requirement 200 on August 29, 1962. It called for an aircraft based on the F4H-1 but with added ground attack capability. The folding wings, catapult attachment points, and arrestor hooks of the naval version were to be retained, but dual controls were to be provided for the crew member in the rear seat. The high tire pressure of the Navy F-4B was unacceptable to the Air Force, and new wider tires with lower pressures were to be fitted. Anti-skid wheel brakes were to be provided, the Air Force considering that even the tail hook would not be enough insurance in case of a landing emergency.

On September 18, 1962, the Defense Department ordered that all Air Force, Army, and Navy aircraft be designated under a common, universal system. This was done because Secretary McNamara was interested in achieving greater commonality between the services. According to one story, he supposedly had gotten hopelessly confused when his aides told him that the Navy and the Air Force had completely different designation schemes, often for what was basically the same aircraft. Under the Defense Department order, the separate naval designation system which had been around since 1922 was eliminated. In particular, this meant that the F4H naval designation for the Phantom was abolished and replaced by F-4. At the same time, the F-110 Air Force designation for the Phantom was also abolished and replaced by F-4. Henceforth, both Navy and Air Force Phantoms were to be designated F-4, with Air Force and Navy Phantoms being distinguished from each other only by series letters. The Navy F4H-1 Phantom was re-designated F-4B, whereas the Air Force F-110A became known as F-4C and the YRF-110A became YRF-4C. At the same time, the separate name Spectre for the USAF's version was eliminated, and from that moment onward, both Air Force and Navy F-4s were named Phantom II.
