Sikorsky Sea Hawk SH-60B is a United States Navy helicopter based on the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The game GTA-V had a plane named Cargo Bob that was based on SH-60B Sea Hawk.
SH-60B is a twin turboshaft engine, multi-mission helicopter mostly used search and rescue, medical evacuation, or for war purposes.
Cargo Bob from GTA-V is not fully based on SH-60B but it did shared a lot of similarity. I will also post other models that Cargo Bob was based upon later.
As for SH-60B, the templates files comes in PDF only. About 10 piece of paper required to build this helicopter model.
