What if the Navy used a spy drone instead of a satellite ...

Japan is considering introducing US spy drones to boost surveillance of its territorial waters near islands in the East China Sea at the center of a bitter dispute with Beijing, Kyodo News said Monday.
The Japanese defense ministry hopes to introduce the unmanned Global Hawk aircraft by 2015 “in a bid to counter China’s growing assertiveness at sea, especially when it comes to the Senkaku Islands,” the news agency said, citing unnamed government officials.
Beijing has been sending maritime patrol vessels into waters around the Japanese-controlled islands, which China claims as Diaoyu, since Tokyo nationalized the chain in September.
China is apparently seeking to prove that it can come and go in the area at will.

What if you used a floating passive sonar platform anchored like they did the USS Ponce?

A new, key addition to American-led naval efforts to ensure Mideast oil keeps flowing has emerged as an unusual mix of a ship combining decades' worth of wear and tear with state-of-the-art technology and a largely civilian crew.
After winning a reprieve from the scrapyard, the USS Ponce was reborn through a rush retrofit earlier this year and turned into a floating base prowling the waters of the Persian Gulf.
It is now getting its biggest workout since refurbishment as the centerpiece for sweeping anti-mine naval exercises under way that serve as a very public warning to Iran.
The Islamic Republic has threatened to shut the Gulf's entrance at the Strait of Hormuz, the route for a fifth of the world's oil supplies, and would likely use mines to do so.
