"This ship is the deterrent that keeps us from having to fight in the first place", Trump said.
USA allies will rest easy, Trump said, but America's enemies will "shake with fear" when they see the Ford cutting across the horizon.
"For years, our government has subjected the military to unpredictable funding, and a devastating defense 'sequester, '" the president said.
Trump will deliver the ceremony's principal address, marking his second visit to the new carrier since his inauguration.
She said: "There is no-one, absolutely no-one, who would be prouder of the commissioning of this mighty ship than the president of the United States, Gerald R Ford".
Construction on the USS Ford started in 2009 and was to be completed by September 2015 at a cost of $10.5 billion.
In the U.S., has commissioned the largest and most expensive aircraft carrier in the world - Gerald R. Ford.
The USS Gerald R. Ford is the 1st member of the next generation of nuclear-powered aircraft carriers and is named after the country's 38th President.
President Trump will be in Virginia this weekend.
President Donald Trump is presiding over the event at which the $12.9 billion state-of-the-art aircraft carrier will be turned over to the Navy.
More than double the electrical capacity and automated equipment means the ship can sail more efficiently with at least 600 less crew members.
The Defense Department explained the US Navy plans to spend $43 billion on developing and building three new Ford-class ships - Ford, the future John F. Kennedy (CVN 79) and Enterprise (CVN 80). "We will win", Trump said. The Navy veteran's presidency was largely about restoring trust in the Oval Office, and that's represented in the Ford Foundation's motto: "Integrity at the helm". The work yet to be completed is expected to cost more than $775 million and take another four years.
The warship is the largest nuclear-powered aircraft carrier in the world, and was emblazoned for the event with a banner proclaiming "Made in the US".
The US Navy has attributed the delays and budget overruns to the ship's state-of-the-art systems and technology, including electromagnetic launch systems for jets and drones that will replace steam catapults.
