Comment: Topic must be covered by WP:RELIABLE and WP:SECONDARY inline sources to demonstrate the need for an article about the topic. So far it only demonstrates passing trivial coverage. microbiologyMarcus (petri dish·growths) 20:23, 12 December 2023 (UTC)

In computer architecture, 30-bit integers, memory addresses, or other data units are those that are 30 bits wide. Also, 30-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
A 30-bit word can also store 5 6-bit characters. Generally if floating-point arithmetic was supported in such systems they had option of using double-precision format of 60-bits. Systems with a 30-bit architecture were heavily used for military and aerospace applications particularly with projects initiated in the 1950/60's.
One of the most notable families of machines to use a 30-bit words were those developed for the Naval Tactical Data System.[1][2] The first machine in the class been the AN/USQ-17 which was designed by Seymour Cray,[1] subsequently variations of this architecture would be used by the United States Navy, the United States Marine Corps, NASA and the FAA for the ARTS III TRACON.[3] This was based around the Univac 8303 IOP (I/O Processor) which could be configured in a multiprocessor configuration, depending on the specific Air traffic control site (New York had the largest). It was also used by several airlines in the form of the UNIVAC 490-494 to provide a Airline reservations system in competition with IBM's Sabre Reservation system.
The unrelated Univac 1050 system was notable for been the largest military order for commercial computers in the early 1960's.[4] It was deployed in Vietnam and other parts of SE Asia and was heavily used with regards to Air Materiel Command logistic supply chain.[5] [6]
The RCA 4100 series was a family of militarized machines that was used in Aerospace operations. The RCA 4101 model been used in the AN/FPQ-6 radar system to provide corrections to the output data. The 4202-S model was built for use in tracking of recently launched Space vehicles.[7]
The Adage Graphics Terminal family was built around a 30-bit processor with up to 32KW of core memory combined with a specialised DAC, vector generator and display.[8][9][10]
