Pence's speech at the Pentagon on August 9 coincided with the release of a Department of Defense report to Congress on the steps necessary to create such a force, since the power to create a new branch independent of the five existing forces lies with Congress.
Jimmy Kimmel said Mike Pence's remarks about forming a separate military branch to beef up satellite defense were not a scene from a movie - but action filmmaker Michael Bay is "on board to direct the whole thing".
"We must have American dominance in space, and so we will", Pence said in his speech at the Pentagon.
"The next generation of Americans to confront the emerging threats in the boundless expanse of space will be wearing the uniform of the United States of America", he said, suggesting that this branch of the military will "carry American ideals into the boundless expanse of space".
The report also calls for the creation of "a Space Operations Force of career space experts who are trained, promoted and retained as space warfighting professionals" to include engineers, scientists, intelligence experts, operators and strategists.
But just previous year, Mattis voiced skepticism concerning the need to create a separate Space Force.
Of course, establishing a new branch is no small undertaking, which has served as the primary argument against President Trump's Space Force from within the Pentagon.
Outlining the basic structure of the Space Force, US Vice-President Mike Pence and Defence Secretary James Mattis said space was vital to the country's national interests.

The car-sized spacecraft will be launched from Florida's Cape Canaveral on Saturday at around 3:50 am eastern standard time. The craft comes equipped with a thick shield made of carbon composite foam and carbon fiber.
Trump 2020 re-election campaign manager Brad Parscale emailed supporters on Tuesday asking them to vote on a Space Force logo which will be sold later on.
Key among these is the creation of US Space Command, a new organizational body that would draw in members of existing military branches.
There is spaceship logo surrounded with red and navy stars. Space Force!' Colbert responded by saying: 'Yes, think of that.
The Space Force plan was praised by iconic American astronaut Buzz Aldrin, one of the first men to land and walk on the surface of the Moon. Not better support for armed forces veterans.
The current branches of the USA military are the Navy, Coast Guard, Marine Corps, Army and Air Force.
Pence says the time has come to establish the new United States Space Force to ensure America's dominance in space amid heightened completion and threats from China and Russian Federation.
In March this year, Mr Trump's National Space Strategy was said to recognise USA "competitors and adversaries have turned space into a warfighting domain".
Those, by the way, aren't the first logos designed for Space Force.
"It is becoming a contested war fighting domain and we have to adapt to that reality", Mattis said as he introduced Pence. The Air Force, which now oversees space programs, and Defense Secretary Jim Mattis had argued in the past against adding to the Pentagon's sprawling bureaucracy.
"We have been warning for years of the need to protect our space assets and to develop more capable space systems", they said in a joint statement.
