However, Kellogg during his remarks also said Trump is not a war hawk and prefers peace.
The RNC is expected to honor active-duty US military troops, veterans and law enforcement as part of the patriotic-themed night.
Pence later is expected to make a case for reelecting Trump and draw contrast with Democratic presidential nominee Joe Biden.
Other speakers include the Vice President's wife Karen Pence, outgoing White House counselor Kellyanne Conway, White House Press Secretary Kayleigh McEnany, Senator Marsha Blackburn and Senator Joni Ernst.
Former US national intelligence director and ambassador to Germany, Richard Grenell, is also slated to speak.
The convention began at 8:30 p.m. EST (12:30 GMT on Thursday) and will last until about 11:00 p.m.
Democratic vice presidential nominee Kamala Harris is expected to give a rebuttal after the RNC.
On Tuesday, the Republicans hammered Joe Biden for his support of wars and reached out to immigrants. Key speakers included President Trump's wife Melania and Secretary of State Mike Pompeo. On Monday, the RNC focused on Trump's economic plan, handling of the COVID-19 crisis and law enforcement with Donald Trump Jr. and former ambassador Nikki Haley as the main speakers.
The RNC kicked off in Charlotte, North Carolina on Monday, but has been a combination of virtual recordings and live segments. Trump has appeared on both nights in live shots from the White House. Melania delivered Tuesday night's speech on the White House lawn before a crowd of family, friends and administration officials and other personnel.
Trump, who was formally nominated on Monday, is scheduled to give his acceptance speech on the south lawn of the White House on Thursday, the fourth and final night of the Republican convention.
