Naval anchorage 2 is an authentic upcoming housing project by Pakistan Navy Benevolent Association (PNBA). The plot files available in the market, whether cash or installments, are not offered by PNBA, but the land provider who were given these plots by PNBA against the land. So, yes, its secure investment, though it may be a long term investment option. The project will take time to complete its land acquisition, and launch officially..
Better and secure option is to go for lumpsum cash option, which you can transfer to your name against full payment with discounts.
For installment option, you have to rely on the land provider to transfer the file to your name after payments have been cleared.
Regarding your question about official announcement, yes there is official announcement on the official website of Naval Anchorage which says Anchorage 2 Thalian is launching soon...
