Features and Advantages
The key feature of Mayport airfield lies in its multifunctionality. Its runway, measuring 2,439 metres in length, is capable of receiving heavy military transport aircraft and other large vessels, providing superior logistical support for the naval fleet. The airfield is the base for several helicopter squadrons, including the Light Airborne Multi-Purpose System (LAMPS), which play an important role in anti-submarine warfare and other maritime operations. The combination of a deep-water port capable of berthing up to 34 ships and a modern airfield makes Mayport one of the most versatile and strategically important US Navy facilities on the Atlantic coast.
