Before its decommission in August of 2003, the Navy’s Aircraft Carrier USS Constellation traveled the world, unleashing its jet fighters almost every day at sea. To launch those fighters, intricate systems of steam catapults were used to accelerate the jets to the flight speeds. These steam engines, below the deck of the ship, produced very high ambient living space temperatures in the control and surrounding rooms, thereby forcing the commander to look for solutions.
The commander had seen Mascoat’s thermal barrier coating, Mascoat Marine-DTM, at a recent seminar while at Newport News Shipyards. He thought it to be an effective solution to his problem on the aging vessel. Thus, the Chief Boatswain’s Mate contacted Mascoat to see if the coating would be effective for their application.
Chief Boatswain’s Mate, Edward Jaso, was assigned to the task of applying the coating at a thickness that Mascoat recommended through an engineered study. A thickness of 80 mils (2.0mm) of Mascoat Marine-DTM was used to coat the walls of the catapult room to reduce the heat transferred to surrounding areas of the ship. Chief Boatswain Jaso used his current paint crew on the vessel to apply the product in a series of 4 coats with an airless sprayer. As a result, crewmembers reported that because of the heat transfer being inhibited, the rooms were a much more comfortable place to work.
