[Ed. – Yes, I know USNS Invincible isn’t really a “spy” ship. Spy has only 3 letters, however, and fits better in a headline. The ship’s mission is to gather technical information on missiles in flight. Invincible has been a T-AGM operated by the Military Sealift Command since 2000. The harassment by Iran we could do without, but this is a positive development, indicating we are making a point of visibly collecting against Iranian missile activity. Iran just concluded one of her biggest annual exercises, a naval exercise which also featured multiple, highly-touted missile launches. Invincible was presumably there to monitor.]
A U.S. Navy surveillance ship had a close encounter with an Iranian navy frigate in the Middle East, CBS News national security correspondent David Martin reports.
The encounter was deemed “unprofessional” but not unsafe because the frigate was on a parallel course with the Invincible at the point of closest approach.
