Development for the Hornet is not happening right now. Overall however there's a fair chance that Hornet development will be quicker than without the Viper due to the additional revenue and all the stuff they can use for both planes.
Geez...it sounds like the bad building contractor robbing Peter to pay Paul scenario: "I need half the money up front to start on your house" but actually, that money is going to finishing the previous house he's working on. So what early access-never to be finished-module is in the works to help fund working on the F-16?
