Boeing said on Wednesday it has begun offering a specialized mobile phone aimed at government agencies and contractors who need to keep communication and data secure.
The Boeing Black Smartphone is based on Google's Android operating system and built into a black, tamper-proof handset capable of accessing multiple cell networks instead of a single network like a normal cellphone, according to Boeing and filings with the U.S. Federal Communications Commission.
The secure phone marks an extension of the communications arm of the Chicago-based aerospace and defense contractor, which is best known for jetliners and fighter planes.
Though the phone is not yet commercially available, Boeing is talking to potential customers after 36 months spent developing the device, said Boeing spokeswoman Rebecca Yeamans.
"We saw a need for our customers in a certain market space" that Boeing could meet with its technology expertise, she said.

Boeing is not naming wireless carriers and handset makers it is working with and not disclosing the price, she said.
The 5.2-by-2.7-inch handset, slightly larger than an iPhone, uses dual SIM cards and can operate on the WCDMA, GSM and LTE frequency bands. It also offers WiFi and Bluetooth connectivity and ports to allow "integrating additional sensors or technology enhancements like satellite connectivity or expanding power," Boeing said.
