President Donald Trump's official unveiling of the US military's Space Force logo was mocked on Twitter Friday for resembling an emblem from a long-running science-fiction TV show.

"After consultation with our Great Military Leaders, designers, and others, I am pleased to present the new logo for the United States Space Force, the Sixth Branch of our Magnificent Military," Trump said in a tweet.

People on social-media outlets pointed to the similar qualities between the Space Force logo and the fictional Starfleet logo from the TV show "Star Trek." According to the show's fans, the shape of the large centered chevron and the accompanying stars mimic the logo from the show, which made its debut in 1966 and spawned a host of movies.

George Takei, the actor who starred in show as Hikaru Sulu, appeared to suggest that the show ought to be compensated: "Ahem. We are expecting some royalties from this," he said in a tweet.

In a statement to Business Insider, a Space Force spokesperson said the symbol "was first used as early as 1942 by the US Army Air Forces."

"Since then, the delta symbol has been a prominent feature in military space community emblems," Space Force Maj. William Russell said in the statement, adding that "the US Space Force seal honors the Department of the Air Force's proud history and long-standing record of providing the best space capabilities in the world."

The centered chevron also appears on the US Air Force Space Command's logo, Space Force's predecessor. Space Force separated itself from the Air Force's Space Command to become the sixth branch of the military, joining the Air Force, Marine Corps, Army, Navy, and Coast Guard. Trump signed the National Defense Authorization Act in December, which authorized a budget for the Space Force.

"Space is the world's newest war-fighting domain," Trump said in the signing ceremony. "Amid grave threats to our national security, American superiority in space is absolutely vital. We're leading, but we're not leading by enough, and very shortly, we'll be leading by a lot."

Interest in the latest branch of the US military reached a fever pitch earlier this year, with many people wondering what the uniforms would look like.
