My comment:
(a) There is absolutely no need to read (1)(b). The (1)(a) does not name the source of the photo, but does indicates approximate time: 8月上旬.
(b) The (1)(a) and (2) share photos of similar angles (side view) of the carrier, whereas (3), a satellite photo, taken from above.
(2) Kyle Mizokami, Here Comes China's First Homebuilt Aircraft Carrier http://www.popularmechanics.com/ ... t-aircraft-carrier/
("A major problem with using ski ramps is that only jet-powered aircraft can launch from them. Planes like the E-2D Hawkeye airborne early warning aircraft and the C-2 Greyhound cargo transport are powered by turboprops and can't generate enough onboard power to launch themselves this way. This will limit the carrier's ability to detect air and sea threats at a distance and remain supplied far from port")
Note:
(a) Only view the photo, and read the quotation. There is no need to read the rest of the text.
