THIS is Barack Obama’s colossal campaign coach – dubbed Bus Force One.

The US president is using the security-laden, bomb-proof vehicle while touring round America’s mid west.

With its tinted windows, it looks more like a mode of transport used by rock stars between stadium gigs.

But the Secret Service has added a few handy extras – including night-vision cameras, tear gas cannons, puncture-resistant tyres and 8inch-thick armour-plated bodywork.The tires are mounted on specially designed rims that can continue to drive even if the tires are missing. Like The Beast, the bus is probably airtight, and likely has an advanced fire suppression system, oxygen tanks, and is built to withstand a chemical attack.

With more room than The Beast, the bus will probably have more defensive tricks up its sleeves than The Beast’s night vision cameras, shotguns, and tear-gas cannons.

The electronics and communications are no doubt state of the art, and are sure to replicate The Beast’s direct satellite phone line to the Vice President and the Pentagon.

The White House has left nothing to chance and even keeps bottles of Obama’s blood on board in case he needs an emergency transfusion after an attack.

There are a few home comforts for the president including a fridge stocked with his favourite snacks – chocolate-peanut bars and Edam cheese burgers.

The £1.3million bus, code-named Stagecoach when Obama is on board, was supplied by Hemphill Brothers Coach Company. It has also provided vehicles for Beyonce, Jennifer Lopez, Madonna and the Pope.

The Secret Service used a fund for transportation and armored vehicles to buy two of these buses from the Hemphill Brothers Coach Company for a total of $2,191,960. No word on whether the company will make more, but Cadillac said they would not make The Beast for any private customers or foreign country saying the design is “very private and secretive.” Chances are these buses are two of a kind and will remain so.

But until the Secret Service releases more details, the real technology inside the Obama bus will remain a mystery.
