Captain Scarlet And The Mysterons

Cloudbase, the Command Headquarters of the Spectrum Organisation.

"A lot of time and money was spent to make this the most secure base known to man."
—Colonel White

Cloudbase is the flying aircraft carrier, operating forty thousand (40,000) feet above Earth, which serves as the command headquarters for the Spectrum Organisation in the Super-marionation programme Captain Scarlet and the Mysterons. Captain Black oversaw its initial construction and assisted in its development. Its location, not actually being in any nation of Earth but instead above ALL of them, is intended to prevent any member nation of the World Government of Earth for using it to advance any political agendas, Cloudbase is controlled by special thrusters keeping it skyborne.

In New Captain Scarlet, the Hyper-marionation programme, the analog to Cloudbase is called Skybase.


Colonel White, Supreme Commander-In-Chief of the Spectrum Organisation, or CINCSPEC, also serves as the Commanding Officer of the carrier itself, with Lieutenant Green as his aide. As a defence for Cloudbase, several Angel interceptor aircraft, flown by the female members of the Angel Flight, are always kept on stand-by status, and launch quickly as soon as they are alerted. The Spectrum senior staff are stationed here for duty, including Captain Scarlet and Captain Blue, and the carrier also carries other aircraft, including Spectrum Passenger Jets.


Cloudbase has several rooms and facilities for Spectrum personnel, including:

  1. The Control Room, where Colonel White and Lieutenant Green customarily work.
  2. A "room of sleep," where personnel can get sleep whenever they may need it.
  3. Lounges where members can relax.
  4. An "amber room," where the Spectrum Angel Interceptor pilots relax and stand by for duty.
  5. A radar room, where watch may be kept for any incoming craft.
  6. A sickbay, including a surgical theatre, manned primarily by Doctor Fawn.
  7. A conference room.
  8. A reactor room, the location of Cloudbase's main power source.
  9. Residential quarters and compartments for all personnel stationed aboard the Base.

Presumably, other onboard facilities include a gymnasium, where personnel can maintain their physical training; a galley and a mess hall, where personnel may prepare and/or eat meals; a firing range, where personnel may maintain their shooting skills; and hangars, fueling facilities, and maintenance shops for Spectrum Passenger Jets, Spectrum Helicopters, Magnacopters, and Angel Interceptors.


Since Cloudbase is so high in Earth's atmosphere, a chance of attack from the Mysterons is unlikely, but since their senior officer Captain Black touched off the War of Nerves, the Mysterons have tried several times to destroy it. In "White as Snow", they even took over a satellite from space and used it to try to destroy Cloudbase when they threatened the life of Colonel White. But Colonel White dispatched Symphony Angel to destroy the satellite, which she did with one of her Interceptor's missiles.

The Mysterons also tried to destroy Cloudbase for a second time; in "Dangerous Rendezvous", after getting Captain Scarlet off board, they corrupted the diamond pulsator that Spectrum had managed to obtain from their complex on the moon with which Colonel White had tried to communicate with them into an "IED," or "improvised explosive device." But Captain Scarlet barely managed to warn Cloudbase in time, and Captain Ochre was able to throw the pulsator out of a window so that it might explode harmlessly, and Cloudbase was saved once again.

The Mysterons were once shown, in "Attack on Cloudbase", to have managed to destroy Cloudbase with their flying saucers, but this attack was revealed to be a hallucination which they had planted in Symphony Angel's mind whilst she was stranded in the desert, and Cloudbase and the Spectrum personnel were all revealed to be safe.

Ultimately, for all its protective facilities and armament, perhaps Cloudbase's best defence and protection is the vigilance of all its personnel.
