AN/UYK-70 was established in 1991 as the Common Open Systems Implementation Program (COSIP). It was a database of computers and sub-elements replacing AN/UYK-43 standard for computer systems to meet naval requirements.[1] An early part of it was the Advanced Display System(ADS) designed to replace for display systems such as AN/UYA-4, and the AN/UYQ-21 was issued in October 1993. SSDS, ACDS, and the later AEGIS systems were the first applications of AN/UYK-70. In 1996 AN/UYK-70 systems were used to supplement AEGIS baseline 3a.

The Q-70 supports the Intel, PowerPC, Sparc, and HP processing families as well as commercial operating systems including Solaris, Windows NT, HPUX and VxWorks. The family architecture is based on a single-board 6U VME RISC processor, currently the 165 MHz Hewlett Packard HP744, which has up to 512 Mbytes (1 GB in two slot units) of dual-ported, error-correcting RAM with HP-UX for non real-time operations, or HP-RT operating systems for Real-Time operations. There are two graphics engine options available, Barco offers 30 million vectors/s up to 2,048 × 2,048 resolution with 12 underlay and 12 overlay planes, while the HP Graphics option provides 31 million pixels/s up to 1,280 × 1,024 resolution and eight underlay and eight overlay planes. The video frame grabber has a 30 Hz frame rate with up to two windows managed by X Window, with the Motif GUI. Originally the ADS used CMS-2 language software later supplemented by, or replaced with, C and Ada.
