Again, there are other priorities for the money.
The CA completely lacks GBAD, how likely do you think it is that the RCN will get GBAD/CUAS systems for warehouses before the CA gets those systems for the troops in Latvia?
Once the CA has systems and figures out what works, it makes sense for them RCN to evaluate those systems against the RCN's requirements.
There may be a lot more money, but it isn't infinite, and the people required to run the projects aren't falling from the skies in abundance.
