WASHINGTON DC – The US Army is taking delivery of a first batch of high-tech combat goggles made by Microsoft Corp., citing encouraging results from testing in the field.

Assistant Secretary for Acquisition Douglas Bush has “cleared the Army to begin accepting” some of the 5,000 sets of goggles, spokesman Jamal Beck said in a statement. Their delivery had been placed on hold over concern about the device’s performance until more rigorous testing took place.

Based on the test results so far the service “is adjusting its fielding plan to allow for time to correct deficiencies and also field to units that are focused on training activities,” Beck said.

Microsoft’s Integrated Visual Augmentation System, or IVAS, is expected to provide a “heads-up display” for U.S. ground forces, similar to those for fighter pilots. The system — a customized version of Microsoft’s HoloLens goggles — would let commanders project information onto a visor in front of a soldier’s face and would include features such as night vision.

The Army projects spending as much as $21.9 billion over a decade on Microsoft’s combat goggles, spare parts and support services if all options are exercised.
