The Phase paint schemes have been used on most passengers equipment – locomotives, passenger cars, and trainsets – as well as some non-passenger cars and non-revenue equipment. Phase schemes generally have red, white, and blue on the sides of equipment, with black or gray sections around the wheels and roof to hide grime. [5]

Before the introduction of the tri-service designation system, the F-4 Phantom II was designated F4H by the U.S. Navy, and F-110 Spectre by the U.S. Air Force.. The Tri-Service aircraft designation system is a unified system introduced in 1962 by the United States Department of Defense for designating all U.S. military aircraft.
This list of United States Tri-Service aircraft designations includes prototype, pre-production and operational type designations under the United States Tri-Service aircraft designation system, which replaced the 1924 Air Force, 1922 Navy, and 1956 Army designation systems in 1962.

One voltage cycle of a three-phase system. A polyphase system (the term coined by Silvanus Thompson) is a means of distributing alternating-current (AC) electrical power that utilizes more than one AC phase, which refers to the phase offset value (in degrees) between AC in multiple conducting wires; phases may also refer to the corresponding terminals and conductors, as in color codes.

In 1962 separate aircraft naming schemes were unified, but out of convenience many numbers carried over. For example, the P-38 Lightning, which also was used as the F-4 and F-5 for reconnaissance and FO in the Navy, became the F-38.
