Which of the following is a disadvantage of using an aircraft to conduct ASW?

• A. Limited range
• B. Invulnerable
• C. Rapid deployment
• D. Large payload capacity

Answer: (A)

Endurance and range determine how long an ASW asset can stay on station and actively search a patrol area. Aircraft can reach distant areas quickly and cover large ocean expanses, which is a major advantage, but they are ultimately limited by fuel, maintenance, and sorties required to rearm or refuel. That means they can loiter over a target for only a finite time before needing to return to base or an air refueling point, creating gaps in surveillance and reducing persistent presence against a submarine’s gradual maneuvers. In other words, limited range is a fundamental drawback when it comes to maintaining continuous ASW coverage with aircraft.

Invulnerability isn’t accurate because aircraft are vulnerable to enemy defenses and environmental conditions. Rapid deployment is an advantage, since aircraft can reach a theater quickly. Large payload capacity is not typically a disadvantage and, depending on the platform, may be more an advantage or a trade-off rather than a drawback.
