Question: The first major project for the Roller Coaster Corporation of America was renamed, and is now called what?
Context: Iron Rattler is a steel roller coaster located at Six Flags Fiesta Texas in San Antonio, Texas.  The ride opened in 2013, replacing The Rattler, a wooden roller coaster, by putting a new steel track on top of The Rattler's wooden support structure.  The distance between the lowest and highest points of the first drop was increased from 124 to and the drop was made steeper by changing the angle to 81 degrees.  The resulting modifications increased the speed of the trains from 65 to .  It is the first hybrid wood and steel roller coaster to feature an inversion, in which riders are turned upside-down and then back upright.  The inversion is a zero-g-roll, which is when the train goes through a combination of a loop and a roll. The Cyclone was a wooden roller coaster that operated at Revere Beach in Revere, Massachusetts, from 1925 until 1969.  When Cyclone was constructed, it was the tallest roller coaster ever built, as well as being the first roller coaster in the world to reach 100 ft in height.  In addition to being the tallest roller coaster of its day, some also claim that it was the largest and fastest roller coaster in the world, with a length of 3600 ft and top speeds between 45 and 50 mph (some dispute the speed record claim and instead award that honor to the Giant Dipper).  Cyclone held the title of world's tallest roller coaster until 1964 when it was surpassed by Montaña Rusa at La Feria Chapultepec Mágico in Mexico City, Mexico. Temple of the Night Hawk is an enclosed roller coaster located at Phantasialand.  Founded in 1988 after 18 months of construction, the ride was originally called ‘'Space Center'’.  The ride led passengers past models of rockets and emulated asteroids and the darkened hall was dimly lit with thousands of tiny spots of light to resemble stars.  Due to the construction of the neighbouring Wurze Town in 2001, the roller coaster was redeveloped with a fantasy jungle theme and was renamed as the "Temple of the Night Hawk".  The roller coaster is now completely dark.  Until 2006 there were some green moving lights and strobe lights in the first lifthill, still present today, but not operational.  In 2008 the Lights on the coaster trains were turned off or broke down and have never been repaired since then.  Till 2010 there was a green laser projection with the outlines of a flying hawk and until June 2012, there were some red strobe-lights at the final brakerun.  In 2011, the park installed new strobe lights in the first lifthill, which broke down after about two months, and were never repaired since then.  The ride has four trains and one spare train for repairs each with seven cars.  Each car has two rows of seats each holding two people.  During the four-minute ride time the trains are lifted by three lift hill chains, 1.174 metres of track.  The roller coaster is therefore one of the longest indoor roller coasters in the World, slightly beaten by "Mindbender" in Galaxyland Amusement Park, Canada.  The hall in which the track is located is around 120,000m³ in size and rests on 180 concrete pillars which are 12 metres deep in the ground.  In the basement of the hall is the ‘'Hollywood Tour’' darkride.  The total investment for the ride was around 15 million DM. Leviathan is a steel roller coaster in the Medieval Faire section of the park at Canada's Wonderland in Vaughan, Ontario, Canada.  It is the first roller coaster designed by Swiss firm Bolliger & Mabillard to exceed a height of 300 ft , putting it in a class of roller coasters commonly referred to as "giga".  At 5486 ft long, 306 ft tall, and with a top speed of 92 mph , Leviathan is the tallest and fastest roller coaster in Canada.  s of 2015 , Leviathan is ranked as the eighth-tallest, and the eighth-fastest roller coaster in the world, and the third-tallest traditional lift-style coaster in the world.  It was the 16th roller coaster to be built at Canada's Wonderland, and the ride's track was completed in February 2012, with the first test run being completed on 15 March 2012.  The coaster opened to season pass holders on 27 April 2012, and to the general public on 6 May 2012. Millennium Force is a steel roller coaster built by Intamin at Cedar Point amusement park in Sandusky, Ohio, United States.  It was the fourteenth roller coaster to be built at the park since Blue Streak opened in 1964.  Upon completion in 2000, Millennium Force broke six world records and was the world's first Giga Coaster, a roller coaster that exceeds 300 ft in height and completes a full circuit.  It was briefly the tallest and fastest in the world until Steel Dragon 2000 opened later the same year.  The ride is also the third-longest roller coaster in North America after The Beast at Kings Island and Fury 325 at Carowinds.  It was the first roller coaster to use a cable lift system rather than a traditional chain lift.  The coaster has a 310 ft , 45-degree lift hill with a 300 ft drop and features two tunnels, three overbanked turns, and four hills.  It has a top speed of 93 mph . Colossus is a roller coaster at Thorpe Park in Surrey, England, and the park's first major attraction.  It was built by Swiss manufacturers Intamin and designed by Werner Stengel as an adaptation of "Monte Makaya" in Brazil, with consultation from Tussauds attraction developer John Wardley.  "Colossus" was the world's first roller coaster with ten inversions; an exact replica, called the "10 Inversion Roller Coaster", was later built at Chimelong Paradise in Guangzhou, China.  It retained its title of having the most inversions on any other roller coaster in the world until "The Smiler" at Alton Towers took the record in 2013. Maverick is a steel roller coaster built by Intamin at Cedar Point in Sandusky, Ohio, United States.  It was the seventeenth roller coaster built at the park since Blue Streak in 1964.  It is notable as being the 500th roller coaster designed by German engineer Werner Stengel and the first roller coaster featuring a Twisted Horseshoe Roll.  Maverick's US$21-million price tag makes it Cedar Point's fourth most expensive roller coaster, behind Millennium Force, Top Thrill Dragster, and GateKeeper.  The 4450 ft course makes it the fourth longest roller coaster at Cedar Point. Apocalypse is a steel stand-up roller coaster located at Six Flags America in Prince George's County, Maryland.  The ride made its debut in 1990 as Iron Wolf at Six Flags Great America before being relocated to Six Flags America and renamed to Apocalypse.  The roller coaster was the first built by Swiss manufacturer Bolliger & Mabillard.  When known as Iron Wolf, the roller coaster held the records of the highest (100 ft ) and fastest (55 mph ) stand-up looping roller coaster in the world before losing them to other roller coasters in 1992 and 1996. Roller Coaster Corporation of America (abbreviated RCCA) is an amusement ride manufacturer based in the United States.  The company's first major project was the Rattler at Six Flags Fiesta Texas in 1992, while their most famous coaster was the Son of Beast at Kings Island, the world's tallest and first looping wooden coaster when it opened in 2000. Son of Beast was a record-breaking wooden roller coaster located at Kings Island in Mason, Ohio.  Built and designed by the now defunct Roller Coaster Corporation of America, it opened to the public on May 26, 2000, and was themed as a sequel to one of the park's other signature attractions, The Beast.  In addition to breaking the world record for speed, Son of Beast was the first wooden hypercoaster in the world with a 214 ft drop and was the second wooden coaster to feature an inversion; Flip Flap Railway was the first, but was long defunct before the ride's opening.
