This means that their military-industrial complex does not sleep on their laurels...
Agreed, But unlike Amercian military industry other nations industrial doesn't have a capability or fund to start in advance.
Most of the companies work on particular technology based on their Military orders and requirements.
Back in 60s, Almost every develped country industries were working and inventing new type of technology because of the Cold War. They knew thier research wont go useless or bankrupt.
There were hundreds of new projects under-developments during the Soviet Era but now Sukhoi and MiGs - They dont work or research on a project unless russian military shown any kind of interest or funding.
Nothing funny here.
LM & Boeing are preparing to win tenders which will be opened post 2026.
That is 15yrs of advance planning.
Preparing for future tenders is always a step ahead, But we never know the outcome.
One of the examples, Is the RAH-66 Comanche program. They spended billions of dollars on the project only to canceled it when it reached operational status. US requirements had changed and they opted for Small drone Helicopters and Endurance UCAVs over Comanches!!!
Changing of time will also change the requirements.
