In our navy, PN should work really hard to strengthen its navy in every possible way by equipping itself with modern navy ships or bigger high tech navy ships. S20 subs & upgraded Augosta 9B are going to do good, but PN should really try acquire at least 2 nuclear submarines as this will add a punch in our navy. About the carrier, I don't think PN will go for air craft carrier any time soon.
In drones, CH5 is a probable because of its capability of carrying heavy weapons i.e. Capable of carrying 16 missiles or bombs & the other possible drone can be Cloud Shadow which too can carry heavy weapons & the most important part of Cloud Shadow is, it is jet powered which allows the drone to travel fast. I would to see both of them in PD.
In airforce, TFX program is a probable for PAF apart from TFX, Chinese fighter are on the top of the list J20 is surely what PAF must be looking at as compared to J31, which I am sure PAF is sidelining as there are no updates on the aircraft since its debut in 2014. I am not saying J20 is fully ready for induction in PLAFF, I am sure J20 still requires some changes & engine is most probable, although I was impressed that the current engine was smokeless as seen in the air show.
In missiles, I am sure Pakistan has not put an end to what they have now, which are fully functional. I am sure they are surely working on long range missiles. Shaheen 3 is an example that Pakistan is working on long range missiles & other types of missiles such as cruise missiles for its ships & submarine & etc.
In the end, it all looks good for Pakistan & many of the latest technology we will see in coming years, such as new air crafts, navy ships, missiles & etc. Good luck to our scientist & engineers. Hope you bring the best.
