Marine aircraft help certify San Antonio
DCMilitary.com
The Navy's newest amphibious ship, USS San Antonio, is undergoing aircraft dynamic interface testing off the coast of Virginia and Maryland as part of the post delivery test and trials period.
These are "'First of Class Tests'" required for each new ship class to be certified to operate with aircraft. They are intended to evaluate safe operating conditions for aircraft aboard ship, without which USS San Antonio cannot fulfill its mission as an aviation element.
The flight deck of LPD 17 can support the Marine Corps' largest helicopter, the CH-53E, in addition to smaller helicopters, such as the CH-46, AH-1H and the UH-1H aircraft. The ship will also launch and recover the MV-22 Osprey tilt-rotor aircraft.
Testing began April 10, and is expected to end in early June with results expected to be released six months after completion of tests.
"Collecting required data from shipboard flight tests from several different types of aircraft onboard USS San Antonio will be used to certify LPD 17 class for safe operating conditions for aircraft aboard the ship," said John Nelson, LPD 17 'First of Class' Ship Suitability Testing Lead Project Engineer.
The dynamic interface test team from Air Test and Evaluation Squadron 21 is working with the Naval Air Systems Command and various supporting units. They are working with the ship's Sailors to document the safe limits of relative winds and ship motion, as well as flight deck layout, markings, lighting and cockpit visual cues.
Successful dynamic testing yields sufficient data to make recommendations relative to aviation certification of USS San Antonio or recommendations for specific ship or procedural modifications leading to her certification.
In addition to the dynamic interface testing, the use of Marine Corps rotorcraft will help evaluators assess the ship's hangar, fuel stations and several other aviation facilities.
"This data helps us tell the fleet pilots how to operate safely and also what ship modifications, if any, need to be made for safe consistent flight operations," said John Nelson.
The USS San Antonio's ability to support the full range of Marine Corps aircraft will be essential to the class' requirement to conduct amphibious assault, special operations or expeditionary warfare missions through the first half of the 21st century. The ship will be used to transport and land up to 800 Marines, their equipment and supplies, by embarked air cushion or conventional landing craft or expeditionary fighting vehicles, augmented by helicopters or vertical take off and landing aircraft being tested this year.
Additional dynamic interface testing with the AV-8B Harrier is tentatively scheduled for 2007.
