Air Mobility Command Tail Codes
Air Mobility Command (AMC) aircraft do not use two-letter identification codes, but instead have the name of the base written inside the tail flash. AMC aircraft also use a different standard to identify the aircraft serial number. They use a 5-digit number in which all 5 digits are the same size. In most cases, the first digit represents the last digit of the fiscal year (FY) and the remaining digits identify the 4-digit sequence number. In cases where more than 10,000 aircraft were ordered in a single year (1964, for example), the complete 5-digit sequence number – without FY identification – is used.
