When it comes military capabilities, having economically sustainable military capabilities is a must
This is because majority of the weapons procured by nation in their lifetime will never be used and provide deterrence value in peacetime.
Here is a lesson from history regarding that
Back in 1970, when India was in work developing its nuclear weapons capability, requirement came for developing an ICBM. This was known Project Valiant. Despite limited funding and technological capability DRDL decided to go head with the program until a smart DRDL Project Manager asked a very valid question to Govt representatives
"Supposing we manage acquire liquid fueled engine technology and our team manages to reverse-engineer it, will govt have finances to sustain it?" . The message was clear and given India's economic situation then and in future the project was terminated and funds diverted to ISRO
It would another 37 years later after success of SRE-1 by ISRO , which validated the most critical know how for ICBM RV, India started on Agni 5 ICBM in 2007

Majority of the missile technologies we have to today has some civilian sector purpose and makes money for the Govt, providing the necessary economic sustainment of these weapons.
Any future military capability for India should ideally come from the private sector or atleast be economically sustainable.
Compare this situation with Hanlands across the Himalayas
While plans being laid for the Great Leap in 1958, CCP leadership fantasized the Great Leap would allow China to reach economic status of Soviet Union and USA, allowing China to build and sustain military capabilities similar to these nations.
Overjoyed with delusional fantasies CCP approved the expensive SSN project Type 091 Program pinning hopes on the Great Leap
(Note - India to this day hasn't built SSNs despite having an operational SSBN, given they so expensive.)
Multiple other missile programs like DF-2 and DF-3 were also approved
Great leap ended in a disaster of with millions of Chinese deaths
Any sane Govt would would have closed these projects and focused on recovery of its people, rather CCP decided to do the opposite by increasing number of missile programs like DF-4 and DF-5 ICBM program and also Chinese human spaceflight program in 1967

End result - all this led to economic crisis and CCP desperately had to sell these missiles for fill its dwindling forex reserves and also the ended up nosiest known SSN , which very fittingly was named Han class

By the looks of it PRC is bound to repeat Great Leap era mistakes while trying to match Washington in number of SSNs and Nuclear powered aircraft carriers
