90% to passBOTH INTERNATIONAL & INLAND For identification purposes at night, U.S. Navy submarines on the surface may display an intermittent flashing light of which color?
A
Red
B
Blue
C
White
D
Amber
AI Explanation
The correct answer is D) Amber. U.S. Navy submarines on the surface are required to display an intermittent flashing amber light for identification purposes at night, as per the International Regulations for Preventing Collisions at Sea (COLREGS). This helps other vessels identify the submarine as a submerged vessel on the surface, rather than a regular surface vessel. The other answer choices (red, blue, and white) are not the correct colors for this specific identification requirement.
