Washington, July 11 (TIWN) The US Defense Security Cooperation Agency (DSCA) has submitted a notification to Congress for the sale of F-35 fighter jets to Japan.

F-35B, a stealth vertical take-off and landing fight jet, could help the amphibious assault ship gain a close aggressive capability similar to an aircraft carrier, reports Xinhua news agency.

The DSCA on Thursday said the sale includes 42 F-35B jets able to be deployed on amphibious assault ships

The US State Department had already approved the sale before DSCA''s submission.

Besides the batch of F-35B, Japan also requested 63 F-35A jets, along with 110 Pratt and Whitney F135 engines, the DSCA said.

"It is vital to US national interest to assist Japan in developing and maintaining a strong and effective self-defence capability," the DSCA said, noting that the proposed sale "will not alter the basic military balance in the region".
