西元1914年1月,伊利亞·穆羅梅茨107號進行首飛,同年2月11日,第二原型(工廠機體編號128)成為伊利亞系列機型第一架載客的飛機,共有16名乘客搭乘,創下當時載客數最多的紀錄。[11][12] 西元1914年6月30日至7月12日,又創下了一個世界紀錄-自聖彼得堡飛往基輔並返航,而兩地距離約1200 公里。第一段航程共時14小時38分鐘,在奧爾沙落地加油,返航途中於諾佛索柯尼基落地加油,返航花費的時間更短,約13個小時。[13] 當對西科爾斯基的讚譽傳到了沙皇尼古拉二世的耳中時,沙皇相當高興,並贈與西科爾斯基聖弗拉迪米爾大公四級勳章(英語:Order of St. Vladimir),當時戰事將近,沙皇額外給了他免役的資格,允許他繼續他的設計工作,並承諾會從國家杜馬撥款十萬盧布資助他的研究。[14][15]7月時,一個在紅村舉辦的國家軍事審查會中,尼古拉二世將伊利亞·穆羅梅茨B型128號軍用原型機命名為「基輔」。[16][17]
One of Sikorsky's prized possessions was a personal gift from the Tsar, a diamond-studded gold watch that arrived later in the mail, also in recognition of his achievements with the Ilya Muromets。 Sikorski retained the watch throughout his lifetime。
