US fighters and bombers conducted a deterrence patrol over the Persian Gulf on May 12, 2019, as a warning to Iran, which the US has accused of plotting attacks on US interests in the region.
During the mission, US Air Force B-52H Stratofortress heavy, long-range bombers were accompanied by F-15C Eagles and F-35A Lightning II Joint Strike Fighters. The bombers and escorts were supported by a KC-135 Stratotanker providing aerial refueling.
US Central Command explained to Business Insider that the flight was intended to send a message to Iran and others that the US military is ready to defend its interests.

The bombers were deployed to the CENTCOM area of responsibility last week after the US reportedly received intelligence showing “clear indications that Iranian and Iranian proxy forces were making preparations to possibly attack US forces in the region,” a US Central Command spokesman said.

While emphasizing that the US does not seek war with Iran, the White House has stressed that any attack by Iran will be met with “unrelenting force.”

As CENTCOM bolsters its firepower, Iran has issued several warnings, at one point calling the USS Abraham Lincoln aircraft carrier a “target” rather than a threat. Iran has not yet, it appears, escalated beyond rhetoric though.
