What is the operational range of an LCAC at a speed of 35 knots?

The operational range of an LCAC (Landing Craft Air Cushion) at a speed of 35 knots is indeed 300 nautical miles. This range is based on the design specifications of the LCAC, which is engineered for high-speed transport of troops and equipment from ship to shore. The vessel's powerful propulsion allows it to achieve substantial distances while maintaining speed, which is crucial for rapid deployment scenarios.

At 35 knots, the LCAC can efficiently navigate through various maritime conditions, utilizing its air-cushion technology to traverse not only water but also beach terrain, enhancing its operational versatility. This capability is critical in amphibious operations, where quick and reliable transportation can significantly impact mission success.

Understanding the operational range helps to plan logistics effectively for military movements, ensuring that forces are supported within the range limits of this craft. The other options suggest either shorter or longer distances that do not align with the known specifications of the LCAC at that speed, hence they do not represent its operational capabilities accurately.
