Brazilian submarines: construction schedule of the 4 conventional submarines
1st submarine ProSub ( Submarine Development Program) of the Brazilian Navy will be launched in 2018. The four conventional submarines are already under construction, in parallel. Nearly 700 people are involved in the construction of the first two. Built in Itaguai near Rio de Janeiro, submarines are the result of a partnership between the Brazilian and French governments. It also provides for the construction of the first Brazilian nuclear submarine propulsion.
Conventional submarines are S-BR model and are based on the Scorpene developed by DCNS, partner of the Brazilian Navy in the program. The S-BR has different characteristics from the original, such as increasing the length, displacement and autonomy.
Here is the current status of the construction of four submarines:

Expected starting date: July 2018
SBR-2
On the 2nd submarine, workers are working at the end of the manufacture of pressure hull sections, and transfer of workshops Nuclep (responsible for the construction of hull sections) to ufem (which are mounted and installed the submarine systems). They also began the manufacture of tanks and internal structures.
Expected starting date: September 2020
SBR-3
The 3rd submarine is in sections assembly phase.
Expected starting date: December 2021
