US establishes space warfare command to ensure dominance in

President Donald Trump has formally launched the US Space Command, which he said will ensure that America's dominance in space is "never threatened," amidst advances made by countries like Russia and China.

The command's establishment comes as the US has grown increasingly concerned about threats to its satellites from countries like Russia and China.

"Those who wish to harm the United States, to seek to challenge us on the ultimate high ground of space, it's going to be a whole different ballgame," he said on Thursday at a White House ceremony marking the command's establishment.

Describing the establishment of the 11th Combatant Command as a landmark moment, Trump said it recognises the centrality of space to America's national security and defence.

Gen John W Raymond will be the commander of the US Space Command, which has been established as the 11th Unified Combatant Command of the American armed forces.

The command will initially consist of just 287 personnel and its final location has yet to be determined. Its responsibilities will be transferred primarily from US Strategic Command, according to CNN.

"It's a big deal. As the newest combatant command, SPACECOM will defend America's vital interests in space -- the next war-fighting domain," Trump, also the Commander-in-Chief of the US military, said.

"SpaceCom will ensure that America's dominance in space is never threatened," he said.

"This is a landmark day, one that recognises the centrality of space to America's security and defence," he said.

The Trump administration has identified Russia and China as the countries who pose threat to the United States in space.

"Our adversaries are weaponising Earth's orbits with new technology targeting American satellites that are critical to both battlefield operations and our way of life at home.

"Our freedom to operate in space is also essential to detecting and destroying any missile launched against the United States," he said.

"Just as we have recognised land, air, sea, and cyber as vital war-fighting domains, we will now treat space as an independent region overseen by a new unified geographic combatant command," said the US president.

The Space Command, he said, will soon be followed by establishment of the United States Space Force as the sixth branch of the United States Armed Forces.

The launch was attended among others by Vice President Mike Pence and Defence Secretary Mark Esper.

"To ensure the protection of America's interests in space we must apply the necessary focus, energy, and resources to the task and that is exactly what Space Command will do," Esper said.

"Establishing the United States Space Command as a unified combatant command is the next critical step towards the creation of an independent Space Force as the sixth branch of the armed forces," he said.

"Assured access to space is vital across the full range of military operations. This step puts us on a path to maintain a competitive advantage in this critical war fighting domain," said Chairman of the Joint Chiefs of Staff General Joseph Dunford.

Notably, it is re-establishment of the US Space Command, which existed between 1985 and 2002.

"Space is the new war-fighting domain and we are under constant threat from hostile foreign actors like China and Russia, who are currently gearing up to take on the United States in space. It's abundantly clear we must take these threats seriously," Congressman Michael Waltz said.

Waltz is a member of both the Science, Space and Technology Committee, and the House Armed Services Committee.
