Is this the big heavy lift booster? The possible moon rocket?
When they add the strap-on boosters to the Falcon 9 it will be called the Falcon Heavy.

Falcon Heavy is the world’s most powerful rocket, a launch vehicle of scale and capability unequaled by any other currently flying. With the ability to lift into orbit over 53 metric tons (117,000 lb)—a mass equivalent to a 737 jetliner loaded with passengers, crew, luggage and fuel—Falcon Heavy can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost. Falcon Heavy draws upon the proven heritage and
reliability of Falcon 9. Its first stage is composed of three Falcon 9 nine engine cores whose 27 Merlin engines together generate nearly 4 million pounds of thrust at liftoff. Only the Saturn V moon rocket, last flown in 1973, delivered more payload to orbit. Falcon Heavy was designed from the outset to carry humans into space and restores the possibility of flying missions with crew to the Moon or Mars.
