While an all-out battle may be the only way to truly determine which country has the strongest military, hopefully, we'll never have to find out. If there isn't a real battle to judge, how does someone determine who has the most powerful military in the world? Is it the number of soldiers in a country's militia? Or the types of technology a country has built to defend itself? Or perhaps their military spending budget? Considering the aforementioned factors, resources like Global Fire Power, The Credit Suisse Report, and Nation Master, have allowed us to rank worldwide military powers with a good level of certainty.
Read on to see which countries made the list of the most powerful in the world, leading up to the strongest.

North Korean leader Kim Jong Un is particularly threatened by the U.S. military presence on the island and expressed his anger in July of 2017 when U.S. B-1 bombers took off from Guam and flew over South Korea as a show of force. While Jong Un and the regime practices launching their ballistic missiles, they are consistently reminded that the U.S. can reach their country by air and sea in a timely response.
Lockheed C-5 Galaxy
The C-5 Galaxy is an absolutely incredible plane that provides the U.S. Air Force with a heavy intercontinental airlift capable of carrying oversized loads with ease.
It's one of the largest military aircraft in the world and is extremely expensive to build. The cheapest model of the C-5 goes for around $100.37 million and can range up to about $224.29 million. It still remains active today but was originally introduced in 1970.
The 226-foot aircraft was built by the Antonov Design Bureau in the 1980s and has since become synonymous in both military and commercial aviation. There was more than 50 of them produced and used around the world.
It was a strategic airlift quad-jet that was the heaviest cargo airplane for thirty years and the second-heaviest cargo aircraft in the world. It was surpassed by the Antonov AN-225 which you'll be able to read about very shortly.
The HK 1, or the "Spruce Goose" as it was more widely known because it was made almost entirely out of birch, was originally meant to be a transatlantic transport aircraft during the Second World War. The only problem was that it wasn't finished in time to actually be put into service.
The U.S. military ended up only flying it once in 1947 and only one prototype was ever built. It's now on display at the Evergreen Aviation and Space Museum.
Blohm & Voss BV 238
The Blohm and Voss BV 238 was a German flying boat built during World War II. At the time, it was the heaviest aircraft ever when it first flew in 1944. The BV 238 had an empty weight of 120,769 pounds, but only one was ever built because of the resources it took to put it together.
It holds the title of being the largest aircraft produced by any of the Axis powers during the war as well.
Antonov AN-225 Mriya
This strategic airlift cargo aircraft is powered by six turbofan engines and is the longest and heaviest plane ever built.
It was originally developed to transport the Buran spaceplane for the USSR in the 80s. It can take off with a maximum weight of 640 tons and has the longest wingspan of any aircraft at the time it was built, and out of any current operational aircraft in the world.
This aircraft was built during the tensest moments of the Cold War and still remains active to this day. In fact, there are 1,000 of them in operation around the world.
Originally developed for the USSR, the Ilyushin II-76 was a multi-purpose, four-engine turbofan airlifter that was supposed to be a commercial freighter but ended up being adopted by the Russian military. It's capable of delivering some of the heaviest machinery and military vehicles in the world.
Convair B-36 Peacemaker
The Convair B-36 Peacemaker was operated by the United States Air Force from 1949 until 1959. It had a fairly short lifespan, but still remains the largest mass-produced piston-engined aircraft ever built.
It had the longest wingspan of any combat aircraft ever built at 230 ft. The B-36 was special in that it was capable of delivering any nuclear weapons in the U.S. arsenals at the time without any modifications. It ended up being replaced by the Boeing B-52 Stratofortress near the end of the 50s.
Boeing C-17 Globemaster III
The C-17 Globemaster III is one of the biggest military planes to hit the skies. The Globemaster III was first delivered in 1991 and was produced up until 2015 before it was discontinued. The per-unit cost was about $218 million and was created by McDonnell Douglas.
It was used for strategic and tactical airlift missions that would often include airdrops of heavy machinery or people and immediate medical evacuations. This thing is an absolute beast.
Let's throw it back to World War I with the Zeppelin-Staaken R.VI which was one of the biggest wooden planes produced during the early 1900s. It was a four-engined strategic bomber that was built in Germany and had one of the earliest closed-cockpit in any military aircraft.
Only six of the 18 ended up even surviving the war as four were shot down, six others were destroyed in crashes and two others had technical difficulties.
The Kawanishi H8K was an Imperial Japanese Navy flying boat used primarily for maritime patrol duties. It was an aircraft that was built for long flights over long ranges and it was usually flying solo without any backup over the ocean.
The Americans nicknamed the H8K "Emily" during the war. If you anyone said "Emily" over the radio it was always in reference to this patrolling plane. It wasn't fully functional until the end of World War II as it didn't see combat until 1942.
It's interesting to note that one of the biggest planes in the world is also one of the oldest. The Convair XC-99 had a design capacity of 100,000 lbs for 400 fully equipped soldiers on its double cargo decks. The XC-99 first took flight all the way back in 1947 and was retired in 1957.
The U.S. Air Force used it as a heavy cargo plane and it was the biggest piston-engined, land-based transport plane ever constructed.
Lockheed Martin C-130J Super Hercules
Any aircraft that has the word "Hercules" in the title, nevermind "Super Hercules," is going to be a force to be reckoned with. The C-130J first took flight in 1996 for the U.S. Air Force and has since been delivered to 15 other nations who have placed orders.
It's a four-engine turboprop transport plane that has been in continuous production longer than any other military aircraft in history. While this exact model is roughly two decades old, the Hercules family has been around for nearly six.
Martin JRM Mars
The Martin JRM Mars is a four-engine seaplane that was popularized during World War II. It was the largest seaplane that was used by the Americans and other Allied forces during the War.
There were only seven of them built despite how impressive and effective they were. Four of the remaining flying boats transitioned into civilian use after the war was over. They turned into firefighting water bombers which made them even more useful. Those models have since been retired.
Boeing KC-135 Stratotanker
There's no easy way to refuel strategic bombers, but that's exactly what the KC-135 Stratotanker's task is. It was used a lot during the Vietnam War for the Americans and would become a huge strategic benefit in Operation Desert Storm.
It's interesting to note that the KC-135 and the Boeing 707 were both developed from the same aircraft (the Boeing 367-80). The 136 ft aircraft became revolutionary in that it was the United States Air Force's first ever jet-powered refueling tanker.
The Kalinin K-7 was a heavy experimental aircraft designed and tested in the Soviet Union in the 1930s. It had twin booms and large underwing pods housing fixed landing gear and machine gun turrets.
There was originally supposed to be a passenger version as well with seats arranged inside the wings. It first flew in 1933 and by the seventh flight, it crashed due to structural failure later that year. The accident ended up killing 14 people aboard and one on the ground.
Caspian Sea Monster
The Caspian Sea Monster was developed by the Soviet Union in the 1960s and was continuously tested until 1980 when it was damaged in a testing accident. At the time, it was the largest and heaviest aircraft in the world for about 20 years.
During the Cold War, the U.S. had many missions that had the sole purpose of figuring out what the Sea Monster was capable of doing. It was nearly undetectable to many radar systems as it would consistently fly below the minimum altitude of detection. Despite being an aircraft, it was assigned to the Soviet Navy and operated by the Soviet Air Force.
Xian H-6 Bomber
The H-6 Bomber was first delivered to the Chinese military in 1958 and has enjoyed quite an impressive and successful career. While the Chinese didn't end up getting too much use out of it, the Iraqi and Egyptian Air Forces certainly did. In fact, the Iraqi Air Force retired the plane in 1991, while the Egyptian Air Force would retire the plane in 2000.
It's a variation of the Tupolev Tu-16 twin-engine bomber that was originally built for the Chinese People's Liberation Army Air Force.
Boeing E-3 Sentry
The Boeing E-3 Sentry is an American airborne early warning and control aircraft. It's used by the U.S. Air Force to provide all-weather surveillance, command, control, communications and constant updates.
The E-3 is distinguished by distinctive rotating radar domes above the fuselage. There was 68 of these built before they stopped production in 1992. The radars used pulse-Doppler technology which played a crucial role in directing coalition aircraft against the enemy in Operation Desert Storm.
NASA Super Guppy
This was the very first aircraft to be made by Aero Spacelines. The plane was designed for cargo, which should be pretty obvious just by having a quick glance. It was the successor to the Pregnant Guppy, and all Super Guppys currently remain in service.
There have been five planes built in two different variants of the Guppy aircraft which have been referred to as "Super Guppy." It's pretty obvious how it got its name, so we won't even go there.
The Junkers JU 390 holds a unique place in the heavy military aircraft category. The German-built plane only flew for two years during World War II (1943-1945) for the Luftwaffe. It had six engines which made the design pretty iconic and was the reason this aircraft has a unique place in military history.
The JU-390 was meant to serve as a heavy transport aircraft, a long-range bomber and a patrol plane for the Germans. It was revolutionary for the time.
Boeing B-52 Stratofortress
The Boeing B-52 Stratofortress is an American, long-range, jet-powered, strategic bomber. It has been in use by the United States Air Force since the 1950s and has the capability to carry up to 70,000 pounds of weapons. Without the need to refuel, the bomber can travel up to 8,800 miles.
Originally built to carry nuclear warheads during the Cold War, it replaced the Convair B-36. The plane has remained active in service since 1955 and as of 2015, 58 were still in active service with 18 in reserve.
