IIRC, even largest variable cycle engines considered for ESAV or LRSA (200 klbs+ TOGW) were smaller than F135.

Part of the appeal of say a tailless aircraft is a reduction in the thrust requirement from the engine(s).

This would require a bigger engine than the F-35:

Also, the language used in the article isn't clear as to whether the variant for the F-35 would have a 3rd stream. Regardless, this (and other) articles are pretty clear - the follow on variants will be larger and more powerful than those for the F-35.

Russian Defense Executive Arrested on Charges of Stealing U.S. Trade Secrets

(Source: Radio Free Europe/ Radio Liberty; issued Sept 05, 2019)

WASHINGTON --- A Russian defense industry executive has been arrested in Italy at the request of the United States on charges of attempting to steal trade secrets from a unit of General Electric based in Ohio.

Aleksndr Korshunov, 57, an employee of the Russian state-owned United Engine Corp and a former Foreign Ministry official, was detained at an airport in Naples on August 30, the U.S. Justice Department said in a statement on September 5.

Korshunov and Maurizio Bianchi, the former director of an Italian division of GE Aviation, are accused of hiring former GE employees to prepare a technical report on jet-engine accessories using the U.S. company’s intellectual property, according to the criminal complaint that was unsealed on September 5.

GE Aviation is one of the world’s largest suppliers of civilian and military aircraft engines. It completed the acquisition of an Italian manufacturer of aviation components in 2013. ...

... Russian President Vladimir Putin called the arrest "unfair competition," local media reported.

... Any patents or intellectual property produced during the course of their consulting work were to belong to Russia, the Justice Department said, citing the employees. "Throughout the consulting, employees allegedly used trade secrets owned by GE Aviation to create the technical report," the statement said. ...

The company is owned by state defense holding Rostec. United Engine and Rostec are both on the U.S. sanctions list. ... The Justice Department is seeking Korshunov’s extradition to the United States for trial.
