I wouldn't underestimate them. Besides silos can be camouflaged as decoys, and the real missiles somewhere else.
Ballistic missile submarine force
China's first SSBN, the Xia 092 class hull 406, was laid down in 1978, launched in 1981 and commissioned by 1983. The JL-1 missile was not ready until the first successful test launch of the missile from the Xia in 1988. Previous launch attempts from 1985 had failed. Its primary weapon is the JL-1 SLBM, with 12 launch tubes, as well as six 533 mm tubes for self defense. Because of only one hull, the PLAN does not possess the capability of the other superpowers to maintain a constant SSBN patrol. The missile's short range also permits the 092 to launch its missiles against regional targets only. Striking targets far away require the submarine to travel dangerously closer to enemy waters. The Xia has since undergone a major modernisation refit, with a new black-coated paint and possibly other improvements with unofficial reports indicating the Xia is now carrying an improved missile, the JL-1A that is alleged to have longer range.
Type 094
The PLAN currently has plans to acquire a new class of SSBN, with a projected number of between three to six vessels. The 094 is believed to have been heavily influenced by Russian assistance. It features 12 launch tubes for the longer ranged JL-2 missile (contrary to the previously speculated 16), which has an 8000 km range that can carry 3 to 4 MIRVs. The 094 would be permitted to patrol nearer Chinese waters, with the ability to launch its missiles against continental US targets.
The Type 094 submarine is capable of carrying 12 of the more modern JL-2s<4> with a range of approximately 8,000 km, and is capable of targeting much of the Western Hemisphere, some of it from close to the Chinese coast. The Type 094 is believed by some western analysts to incorporate a great deal of Russian technology and will replace the Type 092 submarine (NATO reporting name: Xia class) for the People's Liberation Army Navy.
In its 2008 assessment of China's military, the United States Department of Defense estimated that one Type 094 "may soon enter service", and that "up to five" would be in service by 2010.<4> The United States government has expressed concern over these submarines, saying that the Chinese government has not been transparent enough about the program.<5>

F-16s have been downed
http://en.wikipedia.org/wiki/F-16_Fighting_FalconI'll grant you that none of them has been piloted by a US pilot in a dogfight (but by SAMs yes). On the other hand US F-16 have never encountered matching or superior planes like the new 4+ generation. So it doesn't prove anything.

the F-22 isn't combat proven under real circumstances :
In July 2009, the Air Force reported that the F-22 requires more than 30 hours of maintenance for every flight hour, at a cost of $44,000. The Office of the Secretary of Defense puts that figure at 34 hours of maintenance per single hour of flight at a cost of $49,808 per hour of flight.<125> The aircraft's radar-absorbing metallic skin is the principal cause of its maintenance troubles, with skin repairs accounting for more than half of the maintenance.<125> Another source of maintenance problems is that many components require custom hand-fitting and are not interchangeable.<125> The canopy visibility has degraded more rapidly than expected, with refurbishments at 331 flight hours, on average, instead of the required 800 hours.<125> Pentagon officials respond that measuring flying costs for aircraft fleets that have not reached 100,000 flying hours is premature. They say improvements have been made since 2008, and the F-22s are on track to meet key performance parameters by 2010.<125> Air Force Magazine reported that the Washington Post article's 55% capable rate was incorrect and that mission capable rates have been climbing, and by late June stood at 62.9%.<126> And the Air Force Association states that the current mission capable rate is 70%.
