[h1]1. Preface[/h1]
In May 1986, the movie "Top Gun" was released in the United States with the F-14 Tomcat fighter as its selling point. Its star Tom Cruise became famous overnight. His Ray-Ban sunglasses and pilot jacket in the movie immediately became hot-selling products. The English title of "Top Gun" "TOP GUN" originally referred to the American Fighter Weapons School at Miramar Naval Air Base in California, USA. After the movie was released, this name also became synonymous with top aviation fighter pilots. What no one expected was that 10 years later, a racehorse named after this name also performed wonderful performances on a foreign racecourse...

[h1]5. History of fame[/h1]
①Take Off
Maya Heavy Gun was born at Etsuo Kawakami's ranch in Niikōnō, Hokkaido.

②Tough And Go
On January 8, 1995, the 4-year-old Maya Jumbo stepped onto the Kyoto Racecourse and started his debut battle. Since Maya Jumbo was suffering from periostitis at the time, the team chose a shorter distance race with less burden. Although Maya Jumbo, with the legendary jockey Take Yutaka on his saddle, competed as the most popular, he only won 5th place in the end. After that, he was defeated repeatedly until his third victory without a win, when he successfully debuted.

After his debut, Maya Jumbo continued to move towards mud racing, and had a mediocre performance of 1 win and 2 losses in the next 3 mud races. In order to explore Maya Jumbo
The team decided to compete in the next grass court event, the Hong Kong JC Cup (Loyal Hong Kong JCT), where Maya, who had switched from clay court, naturally did not receive much support and ranked fifth in popularity. Although she only won third place in the end, this result also dispelled the team's concerns about Maya's adaptability to grass court.

③Pure Vertical (Pure Vertical Upward/Pulling Onions on Dry Land)
Coming to a venue he was familiar with, Maya Heavy Gun easily won the following Yamayuri Special Prize Race (やまゆりテークス) with a 1.5-length advantage, taking the first step in his legendary career.

In late 2011, Maya Heavy Gun competed in the Kobe Shimbun Cup and Kyoto Shimbun Cup, both of which were the precursors to the Chrysanthemum Award. Although they lost to Tanino Classico and Narita Kingoo by one neck respectively, Maya Heavy Gun also officially obtained the ticket to participate in the Chrysanthemum Award due to its outstanding performance.
On November 5, 1995, the Chrysanthemum Tournament was held as scheduled, and Maya Heavy Gun entered the race with the popularity ranking of 3rd. After the race started, Maya Heavy Gun was in the middle of the pack in the 4th place, and maintained its position advantage until the 4th turn. Then, Maya Heavy Gun maintained its leading position on the final straight, breaking the record set by Narita Shirahito last year with a finishing time of 3 minutes 4.4 seconds, winning its first Grand Tournament and GⅠ victory.

After the Chrysanthemum Festival, Maya Heavy Gun set its sights on the Arima Kinen, the final race of the year. Among the competitors were the popular Triple Crown horses Narita Shirahito and Amazon, as well as other outstanding horses such as Excellent Quality, so Maya Heavy Gun was only ranked 6th in popularity. However, Maya Heavy Gun used the lead-release strategy to stay at the front of the team from the beginning of the race, and eventually defeated a group of strong horses by 2 horse lengths, easily winning the championship, proving his completely underestimated strength.
Since then, Maya Heavy Cannon, which has won two consecutive GⅠ events, was also awarded the honors of the annual representative horse and the best 4-year-old stallion of the year due to his outstanding performance in the autumn.
