B-2 Spirit Stealth Bomber

The U.S. Air Force’s B-2 Spirit stealth bomber is a multi-role heavy bomber capable of delivering conventional and nuclear firepower to any worldwide target by slipping past hostile radar undetected. Since its introduction in 1989, the B-2 and its support systems have undergone incremental technology refreshes to keep the aircraft up-to-date and mission ready with the latest advancements including enhanced communication abilities.

Technology upgrades are necessary to improve the B-2’s effectiveness including its ability to receive encrypted mission information and to communicate with commanders worldwide during the mission.

Upgrading Mission Critical Systems

Mission-critical systems, like the B-2’s Adaptable Communications Suite (ACS) typically require long-term compute availability with the highest degree of dependability in order to support the aircraft’s communications capability and combat effectiveness.
Rugged computing systems are designed to allow reliable operation in unforgiving environments, such as extreme temperatures, strong vibrations, and humid or dry settings.

Upgrading the aircraft’s ACS to address obsolescence started with the Air Force seeking technically advanced, rugged computer systems that reliably operate in a variety of aerial and ground environments with attention to compactness, lightweight construction and ease of access.

Crystal Group Solutions

Crystal Group worked closely with the Air Force to provide rugged compute capability while meeting project timing, security and performance mandates for onboard and ground station computers and displays.

As part of the ACS upgrade, Crystal Group supplied a variety of products, including the RS112 1U Rugged Server, RS112PS18M Rugged 1U Carbon Fiber Server and the RD1119 Rugged Display. The equipment upgrade delivers technology that ensures the B-2 fleet meets current and future communications requirements, giving it the ability to opearte in multiple mission profiles around the world.

Equipment Details

Crystal Group’s RS112 Rugged 1U Server is available with two removable 3.5″ drives or four removable 2.5″ drive bays.


Crystal Group’s RS112PS18M Rugged 1U Carbon Fiber Server features ultra light weight carbon fiber construction with four 2.5″ drive bays.
The RS112 Rugged 1U Server is designed in accordance with MIL Standards 810, 167-1 and MIL-S- 901.  With a lightweight aluminum chassis and a 20” depth, the unit is optimally designed for SWaP-sensitive applications. The RS112PS18M Rugged 1U Carbon Fiber Server offers additional weight savings and a reduced 18” depth.

Both rugged servers feature one expansion slot and leading edge Intel® CPU options. The systems’ modularity allows for easy reconfiguration and versatility. The units provide less weight, less power consumption, and a smaller size that conforms to flexible architecture configurations.

In addition to the rugged servers, Crystal Group supplied the RD1119 Rugged Display for non-flight operational duty. The RD1119 features a 19” display in EIA 1U drawer with SXGA resolution. The LCD display offers 1,000 nit light intensity, low reflectance screen, high ambient contrast and full color.  A special cover glass screen provides high transmissibility and low reflectance to improve sunlight readability.
