MIL-STD-1553 defines a standard bus to be used in many military applications, particularly components in aircraft. The 1553B variant was accepted in 1978 by the United States military and has been used in many projects since then. It describes a 16-bit architecture providing a peak data transfer rate of 16 Mbyte/s. In more recent projects, 1553B is being set aside in favor of industry-standard VME or PCI busses, which offer greater bandwidth and more control features.
The Navy is currently developing the Advanced Avionics Interconnect Technology as a replacement for 1553B, to potentially be used in all military applications for the next millenium. It has a goal of data transfer rates exceeding 1 Gbyte/s over a single optical fiber, reducing succeptibility to EMI.
