Development
Curtiss produced six CS-1 prototypes for the Navy in 1923, which were mostly used for engine tests. Two examples of the improved CS-2 were built the following year and set a number of world speed, distance, and endurance records for seaplanes in its class. The Navy ordered both the CS-1 and CS-2 into production, but when Curtiss tendered with a price of $32,000 per aircraft, Martin undercut them with a tender of $25,200 for each CS-1 and $19,863 for each CS-2 and won the contract. Curtiss refused to provide full sets of drawings and data to Martin, so Martin-built machines were in part reverse-engineered from a Curtiss-built CS-1 provided by the Navy. By the time the Martin-produced aircraft were delivered in 1925–26, the Navy's designation system had changed, and they entered service as the SC-1 and SC-2. Martin-built SC-2s suffered from poor handling characteristics and soon earned the nickname "Sea Cow". Meanwhile, the Naval Aircraft Factory made extensive modifications to the two Curtiss CS-2s leading them to be redesignated CS-3. Further development of the design was carried out by Martin as the T3M and T4M, and eventually by Great Lakes as the TG.

Famous quotes containing the word development:
“Understanding child development takes the emphasis away from the child’s character—looking at the child as good or bad. The emphasis is put on behavior as communication. Discipline is thus seen as problem-solving. The child is helped to learn a more acceptable manner of communication.”
—Ellen Galinsky (20th century)
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
—Lawrence Kutner (20th century)
