SAINT PETERSBURG: Russia’s navy will deploy a total of 26 new ships this year including four carrying Kalibr cruise missiles, President Vladimir Putin said Sunday as the country celebrated Navy Day with a show of strength.

“In total in 2018 the navy should get 26 new warships, motor boats and vessels including four warships with Kalibr cruise missiles,” Putin said in the northwestern city of Saint Petersburg, Interfax news agency reported.

Kalibr missiles fired from Russian ships in the Mediterranean and the Caspian have been used as part of Moscow’s military intervention in the conflict in Syria in support of President Bashar al-Assad.

The navy has already this year taken in eight new ships, Putin added.

The commander of the Black Sea fleet, which is based in Crimea’s port of Sevastopol, Vice-Admiral Alexander Moiseyev said six new vessels including missile ships would be inducted by the end of the year, Interfax added.

Putin reviewed a spectacular annual naval display on the Neva River in Saint Petersburg with 39 warships carrying out manoeuvres.

He told the 4,000 servicemen taking part that the navy “is making a weighty contribution to the fight with international terrorism.

“Of course we will continue measures aimed at strengthening and developing the navy, boosting equipment,” Putin said.

The Navy Day celebrations also included a parade in Russia’s Syrian base of Tartus in the Mediterranean for the second time, involving five ships and the Kolpino diesel submarine, the defence ministry said on Facebook.

Meanwhile, thousands protested in central Moscow on Sunday against a proposed increase to the retirement age.

The retirement age proposal is politically sensitive for Putin, who was re-elected in March, because it has prompted a series of protests across Russia since it was announced on June 14, the day Russia played the first match of its soccer World Cup.

Around 90 per cent of the population oppose the bill, according to a recent opinion poll, and a petition against it has attracted 3 million signatures online.

The proposal to raise the retirement age, to 65 from 60 for men and to 63 from 55 for women, is part of an unpopular budget package designed to shore up government finances that is backed by lawmakers.
