Up to how many GBU-39 or GBU-53 bombs can IBIT test simultaneously with CMBRE?

• A. Four
• B. Two
• C. Three
• D. One

Answer: (A)

The test capacity being evaluated is how many munitions the IBIT setup with CMBRE can evaluate at the same time. This configuration is built with four independent test channels, so four GBU-39 or GBU-53 bombs can be connected and tested concurrently. Each bomb requires its own power, control, data, and arming/safe circuits to be exercised during a test, and four channels allow all of these paths to be evaluated in parallel, which speeds up maintenance and verification.

Testing fewer than four would underutilize the available channels and slow workflows, while attempting to test more than four would exceed the configured parallel testing capability of the IBIT-CMBRE setup.
