I am not sure about other connotations, but I believe the most famous Kitty Hawk is the aircraft carrier.

The aircraft carrier USS Kitty Hawk (CV 63) is the first in a class of three super carriers. Constructed by the New York Shipbuilding Corporation at Camden, N.J., Kitty Hawk was commissioned at the Philadelphia Naval Shipyard on April 29, 1961. It is the second U.S. Navy ship named after the small North Carolina town near which Orville and Wilbur Wright flew the first-ever successful, controlled, powered aircraft on Dec. 17, 1903.

The origin of the name Kitty Hawk is still a matter of local debate. Most people agree that it is a Native American name for this area.
The word originally appeared on English settlers\' maps as \"Chickehawk\" or \"Chickahawk\" in the early 1700\'s. By the late 1700\'s, local residents spelled the name as we do today, with old land deeds referring to settlements as \"Kittyhuk,\" \"Kittyhark,\" KittyHawk,\" and \"Kitty Hawk.\"

First, thank you, that you chose my answer.
The subject is enormous, but I will try to give you a concise answer to aircrafts called "Hawk".
Started with the aircraft developers and manufacturers Curtiss, where in the mid thirties the designer of the P-1 gave it the name of Hawk. They went on developing it, and produced several models. It must have started a trend, there was the twin winged Sparrowhawk, then the P-36 became a production plane, and got the name of Mohawk. In the US the P-40D was named the Warhawk, and in the UK the Kittyhawk. The Kittyhawk was perhaps the most numerous, production started in 1938 and went on until 1944. They also went through numerous modifications, from "D" to "L". (The last one, the P-40L was nicknamed "Gipsy Rose Lee" in the UK.) There were also Tomahawks, Goshawks, Superhawks.
After the war, the name continues, and there are US Airforce Blackhawk, Nighthawk, US Navy Seahawk, Sparrowhawk (helicopter), other helicopters from Sikorszky: Pavehawk and Jayhawk. Other manufacturer is Douglas, with Skyhawks.
