Motorola’s Admiral, the phone maker’s latest Android smartphone, will start selling next week for $99 with a Sprint contract.

In the under-$100 price range, we’re accustomed to seeing flimsy, teeny-bopper touchscreens, but this bad boy seems geared toward the professional and enterprise market.

The specs include a 3.1-inch touchscreen, a 5MP camera, a 1.2GHz processor and a text-friendly QWERTY keyboard. The Admiral will ship with Android 2.3, a.k.a. Gingerbread.

Also, as the militaristic name might suggest, this model is equipped for rugged conditions. In fact, the unit seems reinforced for every naturally occurring consumer-electronics challenge except water, ironically.

In a statement, Motorola said the Admiral is “designed to meet Military Standard 810G for dust, shock, vibration, solar radiation, low pressure and high and low temperatures.” The Admiral also features scratch-resistant Gorilla Glass.

The Admiral is Sprint’s first phone featuring the carrier’s Direct Connect services, a portfolio of push-to-talk features that includes instant one-to-one calling, audio/text alerts for outgoing calls, and multiplayer calling for teams and groups of up to 200 people.

“We know our customers will appreciate this tough Android-powered smartphone that combines 3G data speeds with push-to-talk capabilities. It is designed to offer mobile professionals instant communications and mobile broadband data access when it matters most while being able to withstand the toughest environments,” said David Owens, Sprint’s vice president, product development.

The new phone will appear in Sprint retail stores on Sunday, October 23 and through online Sprint retail channels on November 13.
