Fighter jocks get all the glory. Last week, we introduced you to the 10 most popular fighter jets in the world -- and to the companies that build them and the stocks that profit from selling them. Lockheed Martin's C-130 Hercules isn't a fighter jet -- but it almost looks like one. Photo: U.S. Air Force. Why focus on fighter jets? Mainly because everybody loves to read about them. Heck, everybody loves to go to movies about them. (Remember Tom Cruise grinning from the cockpit of an F-14 Tomcat in Top Gun?) But believe it or not, a company's non-fighter jet products may be more rewarding for investors. Take the C-130, for example. Since 1954, Lockheed Martin has built and sold nearly 2,500 C-130 Hercules transports. At an average cost of $30 million per unit, each one generated nearly as much revenue for Lockheed as the $38 million F-14 did for its builder, Northrop Grumman . And Lockheed has sold three times as many C-130 Hercules transports as Northrop sold F-14s. Lockheed Martin isn't the only company making big money selling glorified cargo jets to the military. To find out who else has mastered this trick, read on. 1. Lockheed Martin C-130 Hercules -- List price: $30 million If a picture is worth a thousand words, then this one tells you everything about just how big a C-130 Hercules really is. Photo source: Wikimedia Commons. Starting at the top, Lockheed's C-130 is hands down the most popular military aircraft (that isn't a fighter jet) on the planet. Today, 951 of these big birds are flying around the world -- 51 more than last year. According to Flightglobal Insight, the C-130 Hercules boasts a 22% global market share in military transports, which is more than three times the share of its closest rival. 2. Textron Beechcraft King Air -- List price: $7.5 million British Royal Air Force Super King Air. Photo: RAF. Speaking of which, the C-130 Hercules' No. 2 rival is Beechcraft's King Air, the world's most popular small turboprop transport. Today, 295 of these aircraft are in service around the world, which is 25 more than last year. That gives Beechcraft (now ownedby Textron ) a 7% share of the global market. 3. Boeing C-17 Globemaster III -- List price: $329 million C-17s in flight. That's a lot of airplane -- and Boeing has sold a lot of them. Photo source: U.S. Air Force. Quickly rounding out America's top three military transport producers is Boeing(NYSE: BA) and its popular C-17 line of transports. Much bigger than Lockheed's C-130 Hercules, Boeing's C-17 "Globemaster" actually only masters 6% of the global market. But at $329 million per unit sold, the 263 C-17s currently in service around the world represent more than $86 billion in sales Boeing has accrued to date... and billions of dollars more in potential future revenues for parts, maintenance, and upgrades. 4. Airbus CN-235 -- List price: $34 million Irish Air Corps CN-235 in flight. Photo source: Wikimedia Commons. Turning now to America's first serious rival in military aircraft -- that are not fighter jets -- our first challenger is European aerospace champion Airbus . Airbus calls its CN235 the world's "lowest cost tactical airlifter," a fact that's helped it win customers among the militaries of more than two dozen nations (and the U.S. Coast Guard, too). Together with the larger C295 model, 253 units of the plane are in service globally, giving this airframe a 6% market share. 5. Antonov An-26 Curl -- List price: $22 million Russian Air Force An-26. Photo: Wikimedia Commons. Russia's no slouch in the air transport department, either, and has several contenders on the top 10 list. First up is this An-26. Nearly three decades after it went out of production, 238 "Curls" remain in service (this figure includes the predecessor aircraft, the An-24 Coke). That's enough to give these turboprops 5% market share worldwide. 6. Ilyushin Il-76 -- List price: $30 million Iranian Air Force Il-76. Photo source: Shahram Sharifi via Wikimedia Commons. The venerable Ilyushin Il-76 is nearly as popular. Russia's answer to the C-130 Hercules, and the workhorse of the mid-1970s Red Army, 176 Il-76s are still in service today (including four apparently returned to service over the past year). This gives the Il-76 a 4% global market share. 7. Antonov An-32 Cline -- List price: $15 million Afghan Army Air Corps An-32. Photo source: U.S. Air Force. Antonov's An-32 "Cline" and An-30 "Clank," (no, they didn't pick these names themselves -- NATO did it for them) were developed from the An-26 and An-24, respectively. They're said to be especially useful for their ability to take off in high-altitude environments, such as Afghanistan. Collectively, the aircraft number 139 around the globe, and command a 3% share of the military transports market.
