If I recall correctly it is because the Omani and Ethiopians dismantled their fleet during the last war, that the Ottomans have decided that it isn't worth it at the moment - which has meant that they're focusing much more on their overland connections with China.This leads to my question with ottomans and triple monarchy working can the triple monarchy not sell them boats and build them a dedicated fleet? If the triple are struggerling to project surely selling ottomans a navy could help.
Btw this isn't me complaining about ottomans just curious about the naval situation.
Personally I agree with you, the Ottomans probably ought to have a fleet, but to really become a naval force at the moment they'd need to outclass
3) The Romans
1,2, and 3 are allies - so they'd have to be outclassed together. If they can form an alliance with 4, then they don't need a fleet - Vijayanagar is paying for their own.
Sadly short of the protected internal reforms the Ottomans are not in a great situation, their main lifelines are their geographic advantage defensively, and the routes to China.
Personally I think the internal reforms do need to include urbanisation in the eastern reaches to establish a more robust control over the Afghans (and effectively create another pool to recruit from) - and focus on securing Central Asia. It isn't Mesopotamia, but working on those areas, and perhaps even engaging in public works to improve access to glacier-melt and other water sources could transform the region.
