F35 is networked heavily, for its sensor fusion and various abilities. It has probably 25 million LOC and is heavily software dependent. It should be viewed somewhat as a closed software product that needs heavy vendor support right from mi

CATL and BYD have more than 50% share of world's battery manufacturing capacity. And the trend is upwards. Same reason china EVs are edging out Telsa and EU EVs out in international market, where LFP is becoming more common.

Pumped hydro storage is approximately cost competitive with new nuclear. It depends on ease of incentives, building permits and finance mechanisms available for building new hydro vs nuclear. Estimated LCOE of new hydro in India for example

There are alternatives for grid storage that are being deployed right now. Sodium or Flow batteries, CAES and underground pumped hydro. As lithium prices increase, alternative technologies will be deployed in scale and come down in cost.
