I was wondering why CJ was worried about the North Korean cannons. What cannon, howitzer, or other artillery piece has a 50 km range? It's not an issue anyone worries about - the dam they can blow is more of a threat, but you can't reload it once blown. The North has zero chance of winning a war, but they can kill a lot of civilians while losing. NK makes the case for first strike for the good of so many people - the Chinese dependency on the USA dollar makes them unlikely to back NK under any circumstance this time.

N.Korea has world's largest artillery force: US The top US commander in South Korea said on Wednesday that North Korea has the world's largest artillery force and could rain fire on Seoul should the communist state decide to provoke all-out conflict. General Walter Sharp's comments came amid rising tensions on the peninsula. Last Saturday the North's military reminded South Korea that its densely populated capital is "only 50 km away" from the border. Sharp, commander of some 28,500 US troops in South Korea, said the North has "an old but very large military that is positioned in a very dangerous place, very close" to South Korea. "They have a very large special operating force. It has the world's largest artillery force that is positioned as far south as possible and that can rain on Seoul today," he told local business leaders. The North maintains 80,000 special forces and is believed to have some 13,000 artillery pieces deployed along the border, Sharp said. Cross-border relations are at their worst in a decade after South Korean President Lee Myung-Bak abandoned his predecessors' policy of providing almost unconditional aid to the North. Pyongyang is also angry at Seoul's announced intention to join a US-led initiative against shipments of weapons of mass destruction. It says any move by its neighbour to join the Proliferation Security Initiative would be seen as a declaration of war. Sharp said US and South Korean troops are prepared to "fight and win" at any moment, stressing they "have operational plans prepared in order to be able to meet any contingencies".

"I was wondering why CJ was worried about the North Korean cannons." Because that is what military analysts, both inside and outside the military talk about. "What cannon, howitzer, or other artillery piece has a 50 km range?" Rocket-boosted can reach 190 km. Even the North Koreans can build those.

"What specific caliber? The 3" naval guns can reach about 16km (extended range to 20km.) 105mm howitzers can get to about 15km (extended range to just about 18km.) Russian and chinese 122mm can reach about 16km (21km assisted.) 127mm naval guns can get to about 24km unassisted (very few extended range shells have been developed for these naval guns, but PGMs reach well beyond 30km.) Russian-type 130mm naval guns can reach just over 27km (only known extended range range ammo is used in coastal mounts, not on ships, and can hit just shy of 35km.) 152mm and 155mm guns, depending on whether they are 39, 45, or 52 caliber pieces, get anywhere between 24-36km unassisted (reaching 30-50km with extended range ammo.) (I got most of this from a few Jane's Armour and Artillery encycs.) Barrel length and propellant charge (and resulting velocity), and shell dynamics (shape, weight, balance, aerodynamics), as well as gun elevation, will determine how far the shell will carry. The 2 range extenders are base bleed elements and rocket assistance. Base bleed elements are slow-burning material that eliminates or greatly reduces the drag on the tail end of a projectile (the base), allowing an improved range. But rocket assistance is just that: a faster burning and higher specific thrust solid propellant "chunk" that exerts considerable extra push to get the shell further away, but often at the expense of accuracy.." strategypage.com
