看Garmin官網上的發布，
United States Air Force selects Garmin® D2 Charlie aviator watch
說是美國空軍將會給U2飛行員提供100支D2 Charlie航空錶，
以作為駕駛艙內的備份GPS設備。
Garmin International, Inc. a unit of Garmin Ltd. (NASDAQ: GRMN), today announced that the D2™ Charlie aviator watch has been selected by the United States Air Force (USAF) for use by the pilots of the Lockheed U-2 aircraft. The high-sensitivity WAAS GPS-enabled D2 Charlie aviator watch incorporates global navigation capability, rich and colorful moving maps and more, providing pilots in the USAF with an exclusive, back-up navigation timepiece in the cockpit.
With a service ceiling of 70,000 feet, the D2 Charlie will provide unique benefits such as barometric-based O2 alerting and GPS-specific features including track, distance to the next waypoint, estimated time enroute and more.
按照上面的說法，D2 Charlie可以在7萬英尺高空提供氣壓高度警告，GPS航路，到下一導航點的距離和時間等資訊。

U2是上個世紀冷戰時代的一款著名偵察機（間諜機），
21世紀它還在服役之中，真是沒有想到。
