Emer-class offshore patrol vessel

After evaluating for three years, the Irish Naval Service ordered the lead ship of an evolved design in 1975. The keel laying for Emer took place on 28 February 1977. The launch followed later that year on 26 September 1977. The keel for the second ship, Aoife, was laid on 3 July 1978 and she was launched 12 April 1979. The final ship, Aisling, had her keel laid on 31 January 1979 and was launched 3 October 1979. == Ships in class ==

Nigeria was decommissioned on 20 September 2013, and was sold at auction for €320,000 to a Nigerian businessman in October 2013. In July 2014, Emer was impounded by the Nigerian Navy because the new owner had failed to secure the necessary military approval before bringing the ship into Nigerian waters. On 19 February 2015, the vessel was commissioned into the Nigerian Navy as a training ship and renamed NNS Prosperity. Libya Aisling was put up for a public auction on 23 March 2017 at the Carrigaline Hotel in County Cork, and was purchased by a Dutch broker for his clients for a reported price of €110,000, there being no other higher bids. As of 10 May 2017, the vessel was listed on a brokerage website with an asking price of $750,000 (€685,000), with the difference between sale price and asking price attracting attention from representative groups. In 2018, Aisling was commissioned, under the name Al Karama (), as the flagship of the naval component of the Libyan National Army. == References ==
