LÉ Emer (P21) of the Irish Naval Service, now known as NNS Prosperity of the Nigerian Navy, was built as a patrol vessel in Verolme Dockyard, Cork, Ireland in 1977.^[1]

After evaluating Deirdre for 3 years, Emer was ordered by the Irish Naval Service in 1975. Commissioned in January 1978, she was named after Emer, the principal wife of Cúchulainn, a legendary Irish folk hero.^[2]

She was an improved version of the sole of class Deirdre and similar to LÉ Aoife (P22) and LÉ Aisling (P23)^{[citation needed]}. She was commissioned on 16 January 1978 and had 35 years of service with the Irish Naval Service.^[2]

Decommissioned on 20 September 2013,^[3] in October 2013 Emer was sold at auction for €320,000 to a Nigerian businessman.^[4]

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.^[5] On 19 February 2015 Emer was commissioned into the Nigerian Navy as a training ship and renamed NNS Prosperity.^[6]^[7]
