The Saab Gripen has had some studies around whether it would be possible to adapt to carrier operation. Several countries seem to have expressed interest, but no commitments have been made yet. From wikipedia:
Saab studied a variant of the Gripen capable of operating from aircraft carriers in the 1990s. In 2009, it launched the Sea Gripen project in response to India's request for information on a carrier-based aircraft. Brazil may also require new carrier aircraft.[74][75] Following a meeting with Ministry of Defence (MoD) officials in May 2011, Saab agreed to establish a development center in the UK to expand on the Sea Gripen concept.[76]... ; further development of optionally manned and carrier versions would require customer commitment.[77][78] On 6 November 2014, the Brazilian Navy expressed interest in a carrier-based Gripen.[79]
