(LEAD) S. Korea holds rare training involving F-35A fighters after N.K. ICBM launch

South Korea's Air Force conducted a rare training involving its F-35A radar-evading fighters in a show of airpower Friday, a day after North Korea test-fired an intercontinental ballistic missile (ICBM).

Defense Minister Suh Wook oversaw the "Elephant Walk" training and ordered troops to maintain "full" readiness based on the "invisible power" of the F-35As, the defense ministry said. It did not disclose the training site for security reasons.

The training marked the first major mobilization of the stealth fighters after the Air Force completed the deployment of 40 F-35As in January.

"Using the F-35A stealth fighters, we should maintain a full readiness posture to achieve an overwhelming strategic victory (in any fight) and deter North Korea's additional actions," Suh was quoted as saying.
