Curtis SC Seahawk History

World War II (1939-1945) called for equal victories at sea and on land, especially for countries that depended on free access to the world's key maritime spaces - such as the United States, Great Britain, and Imperial Japan. To meet this need, many seaplanes and airships were used during the Great Conflict, with designs ranging from pre-war products to completely new developments. As fighting in the Pacific heats up, the United States Navy (USN) seeks to increase its fleet of combat, reconnaissance seaplanes.

One attempt produced the Curtiss SC Seahawk, with 577 eventually built. The first flight of this type was recorded on February 16, 1944, and it entered service the same year. It remained in service until a few years after the war and was not decommissioned until 1949.

As early as 1942, the prospect of a new seaplane for the US Navy was brewing. The United States has been at war since Pearl Harbor in December 1941, and strengthening all weapons is now a priority. Initial interest led the U.S. Navy to commission Curtis Aircraft to develop a pair of prototypes based on the new seaplane design.

The contract, signed on August 25, 1942, less than a month after the company submitted its bid, included the ordering of several service test aircraft to evaluate the viability of the new aircraft under operating conditions.

Introduced in 1942, the XSC-1 product had long been developed to wartime standards, as the series did not officially enter service until October 1944. Officially designated SC-1 Seahawks, they are delivered with fixed undercarriage and then add standard flotation equipment upon arrival.

The first prototypes were delivered to the Alaska-class cruiser USS Guam, which entered service in September of the same year.

In practice, the Seahawk proved to be an excellent seaplane for Navy service and was highly regarded in its field. However, its long development period limited its usability for much of the war, and its first notable actions did not take place until June 1945.

At this point the war in Europe was over, and in a few months Japan would surrender, officially ending the war.

In addition to the SC-1 production model, there exists a proposed SC-2 - a version with a second crew, with a correspondingly modified cockpit and canopy. This version has not been edited, although about nine prototypes were commissioned.

The SC-1 maintains a top speed of 315 mph and cruises close to 125 mph. It has a range of 625 miles and a service ceiling of up to 37,300 feet. Climb rate is 2,500 feet per minute.
