For this you can user BehaviorSubject

export class FleetListService {
    public data: any = new BehaviorSubject('your hard coded data goes here');
    getdata() {
        //do your stuff
        this.FleetListService.next('new data got from server');
    }
}

One of the variants of Subjects is the BehaviorSubject, which has a notion of "the current value". It stores the latest value emitted to its consumers, and whenever a new Observer subscribes, it will immediately receive the "current value" from the BehaviorSubject. Behaviour subject always returns last data. For more info
